The Effect of Chicken Gallus gallus (Domestics) feathers on the sorption properties of polyurethane foam Nadhim A. Abdullah, Hamed A. Hamdi, Abbas Dareb Shaban Bionatura, 2022 A comparative absorption capability analysis was conducted using adapted polyurethane foam as crude oil Sorbents. The used Crude oil has been brought from the west of the Qurna city oil field with A.P.I. equals 22.2- 27. API measures how heavy or light a petroleum liquid is compared to water; crude oil's sorption and absorption ratio amounts are investigated. The findings demonstrate that the absorption ratio of fluff feather to wing feather is very distinct. The fluff feather absorbed much more crude oil than the wings. Moreover, much crude oil absorption causes the three types of feathers to plunge into crude oil. Owing to the disparity of the capillary structures of pure and modified polyurethane and the particular arrangement of the feathers, the absorption of modified polyurethane foam is beyond pure foam. The absorption ratio is saturated at (240-270) % (where the modified foam releases some additional volume of crude oil rather than the saturation ratio). Because of the cross-link density inside the modified foam, the last results were clarified. Also, we analyzed the effect of 10 holes on the absorption ratio in which the absorption is less than the unpinned ratio.
