| Abstract: | Biosorption of heavy metals was carried out using immobilized activated sludge. No significant effect of temperature was observed in the test, while pH and sorption duration exerted important influence on the sorption process. Besides, the sorption process of Cu~(2+) is in accordance with Langmuir isotherm. And a chromatographic effect in the adsorption column performance caused by different sorption affinities of the metal ions was investigated, the sorption capacity of the immobilized sludge for Cu~(2+) was much higher than Cd~(2+) and Zn~(2+). |
