摘要：

Milled-sieved and epichlorhydrin-immobilised Azolla biosorbed ca. 363 and 320 mu 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.
