Abstract
Sequential extraction of a solid material (scale) collected from a wat er still was carried out by using the following chemical reagents; 1 M CH3COONH4, 0.04 M NH2OH.HCl in 25% (v/v) CH3COOH, 30% H2O2 in dilute HNO3 and 7M HNO3. The solid residues after each extraction were collec ted, and then used as sorbents in a radiochemical Zn-65(II) sorption e xperiment. Aqueous Zn-65(II) was found to be predominantly associated with carbonates [and/or hydrous iron(III) oxides] and silicate mineral s in the scale. Organic matter was not of primary importance in Zn(II) scavenging, probably because the organic content of the scale sample was small. Silicate lattices remaining after 7M HNO, treatment did not sorb Zn-65(II).
