Влияние гуминовых кислот на сорбцию цезия природными и модифицированными алюмосиликатами

Abstract

The influence of humic acids on the sorption characteristics of natural (glauconite and clinoptilolite) and modified (NPF-glauconite and NPF-clinoptilolite) aluminosilicates was studied. It was shown that humic acids (HA) almost completely suppress the sorption ability of the natural glauconite and clinoptilolite at HA concentration of 200 mg/l and 2 g/l respectively. The modified aluminosilicates showed caesium distribution coefficients of at least 5•102-103 ml/g at solutions with HA concentration more than 1.5-2 g/l; this allows suggesting them to be a promising sorbents for soils rehabilitation.
