. Sorbents of natural and artificial origin are used to implement sorption methods of water purification. Coal sorbents are widely used in the field of water, air purification and various sorption processes. They have high efficiency in the sorption of organic substances and heavy metals, and can also be used to purify soils and water from petroleum products. One of the most economical ways to use this method is the use of sorbents obtained from production and consumption waste. Of great interest are multi-tonnage renewable agricultural waste, as a promising raw material for the production of sorption materials. The raw material for the pro-duction of such coal sorbents can be waste of plant origin. The paper considers the possibility of using green cotton shoots to produce coal sorbents. The main sorption characteristics of the ob-tained sorbent have been studied: the mass fraction of moisture, bulk density, adsorption activity in crystal violet, oil absorption, buoyancy, as well as a comparative characteristic with analogues.
