Abstract
Adsorption (co‐precipitation) of Ca, Cd, Cu, Ni, Pb on hydrous ferric oxide (HFO) has been investigated under natural conditions. Ferrous iron (ca 6.8 × 10−5 M) present in samples of anoxic lake water was oxidised under controlled conditions to form insoluble HFO. Adsorption of metals at their natural concentrations (10−9‐10−8M; Ca 4 × 10−4M) was determined in the pH range pH 6.5 ‐ 8.5. A large fraction of the Cd (>80%), Cu (ca 50%) and Pb (ca 60%), but not Ni (< 20–30%) and Ca (ca 1%), was adsorbed.This publication has 14 references indexed in Scilit:
