摘要
通过静态和动态吸附试验,研究了GW-F90树脂的除氟性能,确定了树脂的除氟机理。考察了吸附时间、pH、杂质离子对树脂除氟性能的影响,以及解吸剂种类和浓度对树脂解吸性能的影响。研究表明:GW-F90树脂的动态吸附容量为75.3 mg/g,树脂单次吸附的氟去除率达92.7%;采用10%的氢氧化钠溶液对GW-F90树脂进行解吸,解吸率为98.7%。GW-F90树脂具有较好的选择性和除氟性能,可从含氟废水中高效除氟。
The fluoride removal performance of GW-F90 resin was studied through static and dynamic tests,and the effects of adsorption time,initial fluoride concentration,pH and impurity ions on the fluoride removal performance of the resin were investigated.The influence of different desorbers on the desorption performance of the resin was investigated,and the mechanism of fluoride removal of the resin was determined.The research shows that the dynamic adsorption capacity of GW-F90 resin is 75.3 mg/g,the fluoride removal rate of the resin single adsorption can reach 92.7%,and the desorption rate is 98.7%when 10%sodium hydroxide solution is used to desorb the resin.GW-F90 resin has good selectivity and fluoride removal performance,and can effectively remove fluoride from fluoride-containing water.
