摘要
通过表面包覆的方法制备了Fe3S4@PDA复合材料,并研究了该复合材料对Cr(Ⅵ)的吸附特性。考察了溶液pH值、吸附剂投加量、时间等因素对Fe3S4@PDA吸附Cr(Ⅵ)的影响并研究了等温吸附过程。结果表明,Fe3S4@PDA复合材料对Cr(Ⅵ)的较优条件为:pH值为3.0,吸附剂投加量为1.0 g/L,吸附时间为120min。等温吸附过程说明该吸附过程服从Langmuir方程,饱和吸附量为80.645mg/g。
Fe3 S4 @ PDA composites was prepared by self - polymerization of dopamine on surface of Fe3 S4 , and its adsorption performance for Cr（VI） was investigated. Tile effects condition contain pH value of solution, dosage d adsorbent and time on tile adsorption of Cr（VI） by Fe3S4@ PDA were investigated and isothermal adsorption process was studied as well. Results showed that the optimization conditions for Cr（VI） adsorption by Fe3S4 @ PDA composites were pH = 3.0, dosage of adsorbent was 1.0g/L,adsorption time 120min, respectively. The isothermal adsorption process showed that the adsorption process obeys the Langmuir equation with a saturation adsorption amount 80.645 mg/g.
