| 摘 要： | 通过对竹炭吸附水中余氯影响因素的调察,系统研究了竹炭对水中余氯的吸附性能,结果表明:竹炭对水中余氯有较好的去除效果,用炭化温度400℃、粒径小于0.112 mm的竹炭2.0 g,在20℃条件下振荡吸附2 h,处理浓度为25 mg/L余氯水溶液350 mL时,竹炭对余氯的去除率达95.50%。根据Langmuir和Freundlich吸附等温模型对实验数据进行了拟合,结果表明,当余氯浓度在10~30 mg/L范围内,竹炭对水中余氯的吸附符合Freundlich等温线方程。

| Abstract: | The adsorption performance of bamboo charcoal for residual chloride in aqueous solution was studied by virtue of investigated effects of bamboo charcoal on adsorption of residual chloride. Research results indicated that bamboo charcoal had a fairly strong capacity of adsorbing residual chloride. Bamboo charcoal （carbonization temperature 400℃ particle size 〈0.112 mm, dosage 2.0 g） deal with residual chloride solution 350 mL, which initial concentration of residual chloride 25 mg/L, deal time was 2 h. The rate of removing residual chloride by bamboo charcoal was 95.50%. According to Langmuir and Freundlich adsorption isotherm model, the equilibrium adsorption data are fitted by the least square method, the result showed that the adsorption isotherm of residual chloride follows the isothermal adsorption equation of Freundlich, when the concentration of residual chloride was from 10 mg/L to30 mg/L. |
