Abstract EN
The hexavalent chromium Cr(VI) poses a threat as a hazardous metal and its removal from aquatic environments through biosorption has gained attention as a viable technology of bioremediation.
We evaluated the potential use of three green algae (Cladophora glomerata, Enteromorpha intestinalis and Microspora amoena) dry biomass as a biosorbent to remove Cr(VI) from aqueous solutions.
The adsorption capacity of the biomass was determined using batch experiments.
The adsorption capacity appeared to depend on the pH.
The optimum pH with the acid-treated biomass for Cr(VI) biosorption was found to be 2.0 at a constant temperature, 45 C.
Among the three genera studied, C.
glomerata recorded a maximum of 66.6% removal from the batch process using 1.0 g dried algal cells/100 ml aqueous solution containing an initial concentration of 20 mg/L chromium at 45 C and pH 2.0 for 60 min of contact time.
Langmuir and Freundlich isotherm equations fitted to the equilibrium data, Freundlich was the better model.
Our study showed that C.
glomerata dry biomass is a suitable candidate to remove Cr(VI) from aqueous solutions.
