Abstract
It is demonstrated that carbonization of sapropel at the temperature of 700-800 °C may be used in order to obtain carbon-mineral sorbent for wastewater comprehensive purification either from polar substances or from nonpolar ones. Composition and structure for the material obtained were established using X-ray fluorescence and IR spectroscopy, XRD phase analysis, thermal and chemical analyses, low-temperature nitrogen adsorption, mercury porosimetry. Sorption characteristics of the sorbent were determined with respect to a wide range of substances (iodine, methylene blue, heavy metal ions, oil products, phenol, surfactants).
