Abstract:

High-fluorine is the potential restriction factor in application of Antarctic Krill. The study explores the potential of iron-impregnated bamboo charcoal for the removal of fluoride from Antarctic Krill hydrolyzate. Batch experiments were conducted to establish the optimal conditions like particle size，pH，contact time，temperature and dose of the adsorbent. The optimal conditions were as follows：absorbent additive dosage 0.01 g/mL，contact time 60 min，temperature 40 ℃，particle size 40-60 mesh，initial pH. Fluoride level of hydrolyzate can be reduced to 5.1 mg/L under the optimum condition when initial fluoride concentration of 18.7 mg/L is employed. Removal efficiency was promoted to 73% using modified bamboo charcoal ，which is better than unmodified one.
