Effect of the initial pH of cell-free lactic acid fermentation broth (50 mL) on A the uptake of metal ions and lactic acid on 16-h grafted CMC-CSAC (5 g) and B lactic acid purity and recovery percentages in the solution after adsorption. The operation condition was at room temperature for 150 min. CMC-CSAC was prepared by mixing 10 mL solution containing 2% CMC and 20% CA with 5 g CSAC before grafting for 16 h
