摘要

用过氧化氢改性花生壳吸附六价铬,考察了改性花生壳投加量、吸附温度和铬的初始浓度等影响。结果表明,当花生壳的投加量为1.0 g,吸附时间为2 h,温度为60℃,50 mL铬的初始浓度为50 mg/L的吸附效果为最佳,吸附率为80%。红外分析表明,过氧化氢改性花生壳吸附铬的官能团主要为羟基、羧基,包含物理吸附和化学吸附。
        The adsorption of chromium on peanut shell which was modified by hydrogen peroxide was studied.The effects of modified peanut shell dosage,adsorption temperature and initial chromium concentration were investigated.The results showed that when the dosage of peanut shell was 1.0 g,the adsorption time was 2 h,the temperature was 60 ℃,50 mL the initial chromium concentration was 50 mg/L,and the adsorption rate was 80%.Infrared analysis showed that the functional groups involved are mainly hydroxyl and carboxyl groups,including chemisorption and physisorption.
