pH 5.5 was selected as a compromised point with
removal percentage, 0.1 g bio sorbents was achieved to highest
removal percentage and initial Cd2+ concentration is more
efficient in the range of 7 and 10 mg/L, with optimization temperature at 30 C. The Langmuir and Freundlich adsorption
models were used for the mathematical description of the bio sorption equilibrium of cadmium ions to the dried biomass of
alga.
