摘    要:分别用亲水性的聚乙烯胺和疏水性的聚苯乙烯为载体,合成了一系列含不同长度间隔臂的多羟基螯合树脂,并讨论了树脂对硼酸的吸附、洗脱性能,结果表明树脂在中性、弱酸性条件下可较好地吸附硼酸;吸附速率与载体的亲水性和间隔壁长度有关;测定了吸附反应表观活化能以及吸附硼酸后可用0.5N盐酸洗脱。

关 键 词:硼酸  吸附  多羟基树脂  洗脱

Abstract:Polyhydroxy resins containing Schiff base bond with various spacers were synthesized based on cross-linked polyvinyl amine and polystyrcne matrix, and the adsorption-desorption properties for boric acid were also discussed. It showed that the resins can adsorb boric acid under neutral or weakly acid conditions; the adsorption rate constant usually increased with increase of spacer length and hydrophilicity of the matrix; the apparent activation energy and adsorption isothermal curve were determined. The boric acid adsorbed on resins can be eluted with 0.5NHCl.
Keywords:Boric acid  Adsorption  Spacer arm  Polyhydroxy resin
