Abundant resources, natural and organic material – sapropel containing a multitude of different chemical elements has a great potential to be used in different areas, but for now these rich resources are not widely used because of different chemical composition of sapropel research is very few. The article deals with silicon sapropel as a sorbent is able to absorb heavy metals from the solution depending on the time and the concentration of heavy metals in the solution. The sorption studies of heavy metal concentrations were measured in dry sapropel sample using Thermo Scientific Niton® XL2 series of X-ray fluorescence spectrometer (XPS). Also, the heavy metal concentrations in solution were measured by atomic absorption spectrometer AAnalyst 200 (AAS). Get sapropel sorption capacity results are analyzed through absorption capacity curves and Matala ion removal efficiency curves. Also, comparing the results with the initial concentration of heavy metals sapropel and foreign authors used sorbent properties. After thorough research sapropel sorption capacity can be added to the knowledge of sapropel properties utilization.
