Abstract
Glauconite and glauconite sand were used as starting materials. To prepare adsorbents on the ground of glauconite, mixtures of glauconite sand and sodium dihydrophosphate NaH2PO4 at various weight ratios (1 : 1, 2 : 1, 3 : 1, 4 : 1) were subjected to the mechanical activation (MA) in a planetary mill. MA products were studied by methods of X-ray phase and thermal analysis. Degrees of sorption for ions of manganese, cuprum, nickel and zinc were determined from appropriate solutions of sulphates within the concentration range of 60–1000 mg/L.
