Optimization of process variables for the biosorption of chromium using Hypnea valentiae
نویسندگان
چکیده
In this study, Hypnea valentiae, a red alga is used as sorbent for the removal of chromium from aqueous solutions. The biosorption potential valentiae was investigated in batch experiments. process parameters were optimized using response surface methodology. Based on central composite design, quadratic model developed to correlate variables response. most influential factor each experimental design identified analysis variance (ANOVA). optimum conditions maximum are pH – 2.8, temperature 48.2oC, dosage 5.3 g/L, metal concentration 103 mg/L and contact time 27 min. At these found be 94.5%.
