SORPTION ABILITY OF SAMPLES OF HUMIC ACIDS AND THEIR SODIUM SALTS WITH RESPECT TO Cd2+ IONS
نویسندگان
چکیده
The paper presents an analysis of the sorption properties humic acids and their sodium salts isolated from high-moor peat Arkhangelsk region with respect to Cd2+ ions at various pH values. Using adsorption isotherms, volumetric capacity studied preparations was calculated. Langmuir Freindlich mathematical models were used quantify preparations. Calculation sorption, as well statistical data processing carried out using Microsoft Office for Windows, Excel, 2016 software. salts. An estimate rate binding cadmium by sorbents is given, which maximum determined. structural functional features are presented, proving high strength binding, relatively selectivity. Based on results obtained, it assumed that possible develop use based sorbents.

Several studies emphasize the importance of soil organic matter characteristics in hydrophobic contaminant sorption and outline the strong dependence of sorption on organic matter aromaticity. In this study, the role of organic matter aromaticity in phenanthrene sorption was investigated using humic acids (HAs) from compost, peat, and soil that were structurally modified by bleaching, hydrolysi...
