摘要：采用杯[8]、杯[6]、杯[4]芳烃对壳聚糖颗粒进行包覆改性,并对钕离子吸附性能进行了研究.研究发现,杯芳烃主要靠氢键与壳聚糖作用而包覆于壳聚糖表面,杯[6]和杯[8]芳烃包覆壳聚糖对钕离子的吸附量均远高于壳聚糖,而杯[4]芳烃包覆壳聚糖对钕离子的吸附量则较低,但在钕离子的平衡浓度较低时对钕离子的吸附仍高于壳聚糖.同时还研究了杯芳烃包覆壳聚糖的吸附量和pH值的关系.
Chitosan was coated and modified by calix[8]arene,calix[6]arene and calix[4]arene,and the adsorption properties of neodymium ion were studied.The study show that calixarene is coated on the surface of chitosan mostly depending on the effect between hydrogen bond and chitosan.Adsorbance of neodymium ion by chitosan coated with calix[6]arene or calix[8]arene is far more than that of chitosan,while adsorbance of neodymium ion by chitosan coated with calix[4]arene is smaller.However,when the equilibrium concentration of neodymium ion is lower,the adsorbance of neodymium ion by chitosan coated with calix[4]arene is still more than that of chitosan.At the same time the relationship of adsorption capacity of calixarene coated chitosan and pH value was studied.
