端氨基树枝状聚合物对Cr(Ⅵ)的吸附性能研究
Study on adsorption properties of amine-terminated dendritic polymer for hexavalent chromium
摘要
Abstract
With ethylenediamine (EDA) and cyanuric chloride (CNC) as raw materials to prepare the different generations of amine-terminated dendritic polymers (ADP),which was applied to the investigate of adsorption property in Cr(Ⅵ).The results showed that the remove rate of Cr(Ⅵ) were all above 80% treated by the first to fifth generations of ADP.The remove rate of Cr(Ⅵ) was 96% by ADP-3 under the optimum adsorption conditions,in which the pH value was 2,temperature was 45 ℃,adsorption time was 3 h,and the dosage of adsorbent was 4 g/L.Furthermore,the adsorption behavior showed that the adsorption process followed Freundlich isothermal and pseudo second-order adsorption model.关键词
