摘 要:以 NaClO 为改性剂,制备焦粉基碳吸附材料(C-焦粉)。考察了各种影响因素对含氟废水中氟的吸附量的影响:吸附 pH、吸附剂加入量、初始浓度和吸附时间。结果表明:时间为120 min,转速为150 r/min, pH=5.0-5.5时,C-焦粉的吸附性能最佳,且平衡液浓度达到国家饮用水标准。Coke-based carbon adsorbent material was prepared by using NaClO as modifier. Effect of pH, adsorbent dosage, initial concentration and adsorption time on adsorption of fluorin ion in waste water over the coke-based carbon adsorbent material was studied. The results show that: when the time is 120 min, the speed is 150r/min, pH is in the range of 5.0-5.5, the absorption performance of the C-coke is the best, and the balance concentration of fluid can reach to the national standards for drinking water.
