摘要 采用实验室自制磷酸铁,从溶液的p H值、砷初始浓度、温度、搅拌速度等方面探讨磷酸铁对砷的吸附作用。得到磷酸铁吸附砷的最佳工艺条件为:砷初始浓度为0.000 1 mol/L、p H=7、搅拌速度为600 r/min、反应体系温度为80℃和反应时间为1 h,该条件下磷酸铁对砷的吸附效率达到99.6%。为解决饮用水或土壤中砷污染的问题提供一定的参考意义。 The effects of p H,arsenic concentration,temperature and mixing speed on adsorption performances of iron phosphate on arsenic were studied by using self-made iron phosphate. The optimum conditions of arsenic adsorption were initial arsenic concentration 0. 0001 mol / L,p H was 7. 0,stirring speed was 600 r / min,temperature was 80 ℃,reaction time was 1 h,and adsorption efficiency was up to 99. 6%. It was meaningful and helpful to solve the pollution problems in drinking water or soil.
