Abstract
Abstract
A sorbent was synthesized by thermal processing of sapropel residue after the extraction of humic acids, and subsequently modified with polyhexamethyleneguanidine and humic acids pre-isolated from sapropel. The humic sorbent transformations have been studied under air at the temperature range of 20-1000°C by thermal analysis. The presence of various functional groups on the surface of a humic sorbent from sapropel has been confirmed by IR-spectroscopy. Sorption of palladium and nickel ions from water solutions was studied. The value of static capacity of the synthesized humic sorbent for palladium was 38.8±2.7, and for nickel ions was 32.0±1.8 mg/g, respectively. It has been established that the equilibrium of sorption was described by the Freundlich isotherm equation.
