低成本吸附材料对水中氯氟氢菊酯农药的吸附研究

Adsorption of Cyhalothrin Pesticides in Water by Low-cost Material

摘要: 对两种低成本吸附材料米糠和豆渣吸附氯氟氰菊酯进行条件优化。结果表明:米糠吸附氯氟氢菊酯的最优条件为:米糠的投放量为15 g/L、粒径大小为60目、pH为9、温度为40℃、溶液中农药的初始浓度为1.00 mg/L。在最优条件下米糠对氯氟氢菊酯的吸附率可达76.54%。豆渣吸附氯氟氢菊酯的最优条件为:豆渣的投放量为15 g/L、粒径大小为100目、pH为5、温度为40℃、溶液中农药的初始浓度为1.25 mg/L。在最优条件下豆渣对氯氟氢菊酯的吸附率可达85.67%。

Abstract: The adsorption of two kinds of low-cost adsorbents,including rice bran and okara were optimized through the experiment. The optimum adsorption conditions of rice bran:The dosage of rice bran was 15 g/L,the particle sizes was 60 mesh,the pH was 9,the temperature was 40℃,the initial concentration of cyhalothrin was 1.00 mg/L. Under optimum adsorption conditions,cyhalothrin removal efficiency could reach 76.54%. The optimum adsorption conditions of okara:The dosage of okara was 15 g/L,the particle sizes was 100 mesh,the pH was 5,the temperature was 40℃,the initial concentration of cyhalothrin was 1.25 mg/L. Under optimum adsorption conditions,cyhalothrin removal efficiency could reach 85.67%.
