| Abstract: | Milled-sieved and epichlorhydrin-immobilised Azolla biosorbed ca. 363 and 320  mol 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. |
