Abstract
As world practice shows, the most promising and economical way to purify water from organic pollutants is the sorption method. The degree of purification by this method reaches 80–95% and depends on the chemical nature of the adsorbent, the area of the adsorption surface and its availability, as well as on the chemical structure of the substance and its state in water. Therefore, the creation of cheap effective sorbing materials of a wide spectrum of action using available raw materials of natural and plant origin is one of the most promising ways to solve this problem.It has been established that sorbents – corn cobs, grain waste, buckwheat husks from 7.2 to 14.1 g/g, the lowest oil absorption – birch and activated charcoal – have the greatest oil absorption capacity. The walnut shells with birch and activated charcoal values ranging from 1.3 to 2.1 g/g had the lowest water absorption capacity.
