Fig. 7From: Metal ion removal using a low-cost coconut shell activated carbon bioadsorbent in the recovery of lactic acid from the fermentation brothEffect of CMC-CSAC loading on A adsorption capacity of metal ions, glucose, and loss of lactic acid and B lactic acid purity and recovery in the solution after adsorption. The 16-h grafted CMC-CSAC (varied amount in g) was soaked in 50Â mL lactic acid fermentation broth (pH 6) at room temperature for 150Â minBack to article page
