摘要：

Cadmium and zinc biosorption by Chlorella homosphaera cells were tested under laboratory conditions, in a range of concentrations from 0.5 to 14.0mg/l. The results indicated two distinct phases for cadmium biosorption: a rapid phase probably associated with metal adsorption around the cell wall and a slower phase associated with the metal transport into the interior of the cells. For zinc biosorption these phases were not well defined probably due to the metabolic use of this metal by the cells.
