Eco-friendly synthesis of magnetic activated carbon from used water filter cartridges for efficient methylene blue adsorption Dilip D. Anuse, Suryakant A. Patil, Ashwini A. Chorumale, Akanksha G. Kolekar, Prachi P. Bote, Laxman S. Walekar, Mukund G. Mali, Samadhan P. Pawar Cleaner Water, 2025 Using activated carbon (AC) derived from used water filter cartridges (UWFC), we developed a waste-to-resource method to remove dyes from water. Mild reactivation at 400 ° C for 1 h produced AC-UWFC, which was subsequently transformed into magnetic activated carbon (MAC-UWFC) for efficient adsorption of methylene blue (MB). Characterization confirmed a mesoporous structure (BET: 404.78 m 2 g − 1 ) with high stability. Optimal adsorption occurred at a pH of 8, using 0.2 g of MAC-UWFC over 1 h. Adsorption followed the Langmuir isotherm (227.27 mg g − 1 ) and pseudo-second-order kinetics. MAC-UWFC maintained an efficiency of 92.32% after eight cycles, demonstrating its effectiveness in wastewater treatment.
Activated carbon from pencil peel waste for effective removal of cationic crystal violet dye from aqueous solutions Dilip D. Anuse, Suryakant A. Patil, Ashwini A. Chorumale, Akanksha G. Kolekar, Prachi P. Bote, Laxman S. Walekar, Samadhan P. Pawar Results in Chemistry, 2025 • Waste Pencil peel-derived activated carbon (PPAC) was developed as a cost-effective and eco-friendly adsorbent for removing Crystal Violet (CV) dye from wastewater. • PPAC achieved an impressive 99.5 % removal of CV dye at an optimized pH of 7.0, treating a 100 mg/L solution with 200 rpm agitation in just 55 min. • The adsorption followed the Freundlich isotherm model for multilayer adsorption and adhered to a pseudo-second-order kinetic rate. • The simplicity of preparation, excellent reusability over five cycles, and high efficiency make PPAC a promising and economical solution for CV dye removal from aqueous solutions. In this investigation, the pencil peel (PP) is utilized as a scavenger for adsorptive removal of crystal violet (CV) dye. Pencil peel activated carbon (PPAC) is produced through a straightforward physical activation method by annealing pencil peel in a muffle furnace at 300 °C. The prepared PPAC shows the mesoporous nature having specific surface area of 217.44 m 2 g −1 . The highest uptake of CV dye was observed at equilibrium as working solution pH-8.0, CV dye concentration-100 mg L -1 , the PPAC dosage-0.25 g at 200 rpm speed. The observed experimental results align with the Freundlich adsorption isotherm model, suggesting of multilayer adsorption. The kinetic study attributes the uptake rate adheres to the pseudo-second-order kinetic rate model (regression coefficient, R 2 = 0.99).
Adsorptive Removal of Methylene Blue Dye by Annealed Waste Foundry Sand Chandrashekhar R. Patil, Suryakant A. Patil, Anita K. Tawade, Bhagyashri B. Kambale, Shivaji N. Tayade, Sharad S. Patil, Dnyandev N. Zambare Asian Journal of Chemistry, 2024 Under optimized experimental conditions, the efficient removal of methylene blue dye from annealed waste foundry sand as adsorbent was carried out. The X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Field emission scanning electron microscopy (FE-SEM) and partical size analysis were used to confirm the crystalline structure, composition and morphology of the prepared sorbent. The sorbent achieved its highest adsorption capacity by interacting with an aqueous solution contaminated with methylene blue dye. A comparison was made between the sorbent and three annealed sands based on their dye removal efficiency adsorption data over time. By using Langmuir and pseudo second-order kinetic models to the sorption data, it is observed that both physical and chemical processes can influence the removal process. According to experimental data, annealed waste foundry sand (WFS-300) has a high adsorption efficiency and methylene blue adsorption follows.

Dynamic adsorption of toxic indigo carmine dye on bio-inspired synthesised Fe3O4 nanoparticles: kinetic and thermodynamic study Suryakant A. Patil, Pramod D. Kumbhar, Sandip K. Patil, Madagonda M. Vadiyar, Umesh P. Suryawanshi, Chitra L. Jambhale, Mansing A. Anuse, Jin H. Kim, Sanjay S. Kolekar International Journal of Environmental Analytical Chemistry, 2022 The bio-inspired synthesis of Fe3O4 nanoparticles using a common kitchen waste, Bengal gram bean (Cicer arietinum L.) extract (BGBE) for enhanced adsorption of toxic indigo carmine dye is reported. Synthesised adsorbent was characterised by FTIR, FE-SEM, XRD, BET and XPS to understand its meticulous properties. The Fe3O4 adsorbent shows fascinating surface area of 78.61 m2 g−1 with a pore volume of 0.25 cc g−1 at P/P0 = 0.98 and displayed nanograin like morphology. The efficiency towards adsorption of toxic IC dye was found up to 99.71 ± 0.35% within 40 min at pH 7 with 0.25 g of Fe3O4 nanomaterials having the 299 ± 2 K surrounding temperature. The Langmuir monolayer adsorption capacity was found to 393.7 mg g−1 at the stroke speed 150 rpm. The experimental data follows the Freundlich adsorption isotherm. Kinetically the uptake rate of IC dye follows pseudo-second-order kinetic model. The thermodynamic study reveals that IC dye adsorption process is spontaneous and endothermic in nature.
Reutilization of carbon from exhausted water filter cartridges (EWFC) for decontamination of water: An innovative waste management approach Prachi P. Bote, Siddharth R. Vaze, Chandrashekhar S. Patil, Suryakant A. Patil, Govind B. Kolekar, Mahaveer D. Kurkuri, Anil H. Gore Environmental Technology and Innovation, 2021 Since from the last couple of decades, the waste and its management has became the most prominent problems that the world is facing serious issues nowadays. Most of the waste in the environment can be reutilized very easily via simple physical/chemical treatments. Under this, we have proposed a novel, simple, economical, sustainable, and renewable approach for cleaning polluted water by proper utilization of carbon from the exhausted water filter cartridges (EWFC). The activated carbon (AC) from the environmental EWFC was obtained through simple reactivation by a moderate physical treatment in the furnace (400°C; 1hr). The results from XRD,FE-SEM, BET, RAMAN, and TEM characterization bear out the successful generation of AC from EWFC (AC-EWFC). In the proposed work methylene blue (MB) dye was used as a model pollutant. To estimate the maximum adsorption capacity of AC-EWFC, a batch adsorption technique was implemented and it was found to be 55.62 mg.g−1. The influence of various core parameters like solution pH, amount of AC-EWFC, MB dye concentration, and the interaction period was carried out. Furthermore, AC-EWFC was tested for kinds of traditional as well as emerging contaminants such as dyes, pharmaceuticals, metal ions and it showed interesting results by an unconventional method. Moreover, the study was employed for real wastewater effluents samples from industries. Most importantly, AC-EWFC adsorbent showed good results for the kinds of pollutants, and support to carbon reutilization from EWFC is possible with nominal treatment and can be used for environmental remediation on a commercial scale.
A Pongamia pinnata pods based activated carbon as an efficient scavenger for adsorption of toxic Co(II): kinetic and thermodynamic study Suryakant A. Patil, Sandip K. Patil, Ashish S. Sartape, Sagar C. Bhise, Madagonda M. Vadiyar, Mansing A. Anuse, Sanjay S. Kolekar Separation Science and Technology Philadelphia, 2020 A porous and high surface area-activated carbon based on Pongamia pinnata pods (PPP) was synthesized using a chemical method. The synthesized material was characterized using FTIR, XRD, BET, SEM, EDX, XPS and TGA. Plausible adsorption mechanism of Co(II) on PPPAC was evaluated systematically. The effect of various contributing parameters were investigated through batch adsorption experiments. Results reveal that the equilibrium was attained within 360 min having 0.35 g PPPAC amount at pH 6 and the maximum equilibrium capacity was observed 190.30 mg/g. Kinetically adsorption of Co(II) was best described by pseudo-second-order-model. The equilibrium data well suited with the Langmuir isotherm model and thermodynamic parameters indicate that the process was spontaneous and endothermic in nature. Graphical Abstract An inexpensive strategy for waste-to-useful for preparation of porous high surface area-activated carbon using concentrated H2SO4 as an impregnated reagent.
