Abstract
A vast array of biological materials, especially algae
have received increasing attention for heavy metal removal. Algae
have been proven to be cheaper, more effective for the removal of
metallic elements in aqueous solutions. A fresh water algal strain was
isolated from Zoo Lake, Johannesburg, South Africa and identified as
Desmodesmus sp. This paper investigates the efficacy of
Desmodesmus sp.in removing heavy metals contaminating the
Wonderfonteinspruit Catchment Area (WCA) water bodies. The
biosorption data fitted the pseudo-second order and Langmuir
isotherm models...
