摘要：

Maximum biosorption of Ca2+ was at 50 mg Ca2+ l(-1) with both Anabaena fertilissima (2.8 mg Ca2+ g(-1) dry wt) and Chlorococcum humicola (4.4 mg g(-1)). Such Ca2+-treated biomasses, accumulated, respectively, 7 mg F g(-1) DW from an aqueous solution of 10 mg F l(-1) and 4.5 mg F g(-1) DW from 15 mg F l(-1). Data for both Ca2+ and F- biosorption fitted the Langmuir adsorption isotherm indicating monolayer adsorption at a constant energy.
