摘要
采用化学共沉淀法合成了Fe_(3)O_(4)纳米粒子,然后用碳二亚胺将聚丙烯酸接枝,再以二乙烯三胺(C_(4)H_(13)N_(3))为表面功能化试剂制备氨基功能化磁性Fe_(3)O_(4)@PAA@DETA,在不同温度和pH的条件下,研究其对Pb^(2+)的吸附效果,吸附率可达92.74%。
Fe_(3)O_(4)nanoparticles were synthesized by chemical co-precipitation method,then polyacrylic acid was grafted with carbodiimide,and then diethylenetriamine(C_(4)H_(13)N_(3))was used as surface functionalization reagent to prepare amino functionalized magnetic Fe_(3)O_(4)@PAA@DETA Under different temperature and pH conditions,the adsorption effect of Pb^(2+)was studied,and the adsorption rate could reach 92.74%.
