"Effective and affordable sorbents produced from natural organic raw materials and waste products of agricultural and livestock origin, because these sorbents are part of existing ecosystems and, therefore, best meet environmental requirements, in order to ensure the rational nature management and preservation of consumer properties of water resources. For the solution of actual problems, such as the removal of oil and oil products from water surface, as sorbents was investigated by the waste processing of leather and agricultural industries: wool (sheep and goat) and feather (chicken and waterfowl). It is established that application of organic and mineral acids at certain concentrations , for treatment of wastes from the processing of wool allows to obtain sorbents directional spectrum for removal of oil products (such as diesel gas oil and engine oil) and oil from water. The modifiers of wool and feathers obtained after the chemical treatment, was used to study the sorption of oil and oil products from water surface. It was determined by sorption characteristics of the modified sorbents, such as oil capacity and moisture absorption. The kinetics of sorption–desorption of oil, which showed that the greatest degree of absorption is observed for the first 10-15 minutes. It is found that wastes from goat and sheep wool have a 90% holding capacity that persists in time. It was revealed the effect of temperature on oil absorption capacity of the sorbent and the calculation of heat of adsorption. The temperature increase leads to a reduction of the capacity of emulsified oil, reducing the degree of purification by 15-30%."
