Cellulose-containing waste from the agricultural industry modified by chemical methods is capable of adsorbing metal ions no worse than industrial sorbents (ion exchangers, activated carbons, zeolites, etc.). A wide range of methods for modifying plant raw materials makes it possible to obtain effective sorbents that are environmentally friendly and biologically inert. Proposed technologies of lignocellulosic sorbent manufacturing are highly economically feasible and, additionally, eco-friendly, because they ensure the proper utilization of agricultural wastes, which are very widespread in Ukraine.
