摘　　要：以氧化石墨烯、FeCl2·4H2O和FeCl3·6H2O为实验原材料,通过碱性共沉淀法制备磁性氧化石墨烯复合材料(Fe-GO)。探究不同的投加量、pH、温度和吸附时间对Fe-GO吸附制革废水中Cr3+的影响。结果表明:Fe-GO对Cr3+吸附的最适宜条件为Fe-GO的投加量为30mg,温度为30℃,pH为5,吸附时间为120min。The magnetic graphene oxide composite(Fe-GO) was prepared from graphene oxide, FeCl2·4H2O and FeCl3·6H2O by alkaline coprecipitation. The effect of different dosage, pH, temperature and adsorption time on Cr3+ removal in tannery wastewater was explored with Fe-GO. The results showed that the best adsorption rate of Cr3+ was obtained under the optimal condition, including the Fe-GO dosage 30 mg, the temperature 30 ℃, the pH 5, and the adsorption time 120 min.
