What is Obtaining Sorption Material from Sorghum for Aqueous Solutions Purification from Heavy Metals about?

## Abstract The paper presents the results of using straw (stalks) of sorghum as a sorbent for removing heavy metal ions of Cu (II) from aqueous solutions. The physical and chemical analysis of sorghum has been carried out. The modification of plant materials by exposure to a temperature of 130-150 ° C is proposed. Thermal activation allows obtaining a highly developed surface of the sorghum microstructure and increasing the total pore volume and their average diameter. The regularities of the effect of the concentration of the modified sorbent and the differences of its dispersed particles on the efficiency of water purification are investigated. The purification of an aqueous solution containing 50 mg/dm^3^ of Cu^2+^ ions was 95% under using a thermo-treated sorghum of 0.63–0.1 mm in an amount of 2.5 g per 100 ml of an aqueous solution. Thermal modification of sorghum allows you to get an effective sorbent and immediately solve two environmental problems, such as wastewater treatment and utilization of plant waste.
