改性杨絮纤维素对重金属离子的吸附
Adsorption of heavy metal ions by modified populus cellulose
摘要
Abstract
Amidoxime populus cellulose (AOPC) was synthesized by two-step method,and FT-IR was used to investigate the structure.AOPC was used to absorb heavy metal ions in potassium dichromate solution water and the effects of absorption capacity for Cr6+ such as adsorption time,pH of the solution and concentration of metal ions were analyzed.The results showed that the adsorption capacity of Cr6+could reach to 70.6 mg/g when concentration of potassium dichromate solution was 1 g/L,and pH was 2.The adsorption process of Cr6+ was in accordance with the Langmuir adsorption isotherm,indicating the adsorption effect of heavy metal ions by modified poplar was good.关键词
