摘要
通过静态试验研究了高质量浓度Cl-(1000 mg.L-1)和HCO3-(2000 mg.L-1)对活性氧化铝吸附F-(10 mg.L-1)的动力学特性影响.结果表明:高质量浓度Cl-使活性氧化铝吸附F-速率加快,吸附量增加;高质量浓度HCO3-有相反趋势.建议采用活性氧化铝吸附除氟法作为煤层气产出水F-净化工艺时,考虑高质量浓度Cl-和HCO3-效应.
Activated alumina （AA） is widely used for defluoridation. Batch experiments were carried out to investigate the influence of Cl-（1000 mg· L-1） and HCO3- （2000 mg·L-1） on adsorption kinetics of F-（10 mg·L-1） on AA in coalbed methane co-produced water （CBMW）. The results show that in the presence of Cl- the adsorption rate and the equilibrium absorption capacity increase, but in the presence of HCOa- both the quantities decrease. These effects should be considered when one treats CBMW.
