A sorbent by thermal processing sapropel residue, after the extraction of humic acids, subsequent modification with polyhexamethyleneguanidine and pre-isolated humic acids was synthesized. The transformations of the carbon-mineral humic sorbent at a temperature of 20-1000°C in air have been studied by thermal analysis. The presence of various functional groups on the surface of a carbon-mineral humic sorbent from sapropel is confirmed with an IR-spectroscopy method. Sorption of petroleum from water solutions was studied. The static capacity value of the synthesized humic sorbent for petroleum is 85.5±0.3 mg/g. It is established that the process of sorption is described by the equation of Freundlich isotherm. |
