Abstract

Milled-sieved and epichlorhydrin-immobilised Azolla biosorbed ca. 363 and 320 μmol^- Cu²⁺ g^-1 from a 100 mg 1^-1 solution. Efficiency of Cu²⁺ removal by columns was in the order epichlorohydrin-immobilised Azolla>milled-sieved Azolla>untreated Azolla. The 2.5 g epichlorohydrin-immobilised Azolla column demonstrated complete metal sequestration from ca. 12 1 of influent 5 mg Cu²⁺ 1^-1 and was still at less than 75% saturation even after ca. 22 1 had passed through the column. EDTA effectively desorbed Cu²⁺ with a ca. 55-fold decrease in volume.
