| 摘 要： | 通过对竹炭吸附水中余氯影响因素的考察,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<0.112mm的竹炭2.0g,在20℃条件下振荡吸附2h,处理浓度为25mg/L余氯水溶液350mL时,竹炭对余氯的去除率达95.50%。根据Langmuir和Freundlich吸附等温模型对试验数据进行了拟合,结果表明,当余氯浓度在10～30mg/L范围内时,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 investigating impact factors in regard,and results indicated that bamboo charcoal had a fairly strong capacity of adsorbing residual chloride.Bamboo charcoal of 2.0 g,under temperature 400oC and with particle size<0.112 mm,treated residual chloride solution of 350 mL,whose concentration was 25 mg/L,and after 2 h at the temperature of 20oC,removing rate of bamboo charcoal to residual chloride was 95.50%.Acc... |
