Abstract Milled-sieved and epichlorhydrin-immobilised Azolla biosorbed ca. 363 and 320 μmol Cu2+ g−1 from a 100 mg l−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 l of influent 5 mg Cu2+ l−1 and was still at less than 75% saturation even after ca. 22 l had passed through the column. EDTA effectively desorbed Cu2+ with a ca. 55-fold decrease in volume.
