摘要
实验表明，用乌桕籽壳制得的活性炭通过氧化和化学改性处理，表面基因发生了变化，尤其是氧化改性活性炭表面含氧官能团数量比未氧化处理的活性炭增加一倍左右，羧羟基比值高近四倍炭表面极性增大，对某些有一定极性的溶质吸附容量增加，将其用于无氰镀锌老化槽液净化时效果显著。
This paper studied the change fo surface radical of activated carbon which made from fruit shell of chinese tallar tree.It indicared that after cxidation and chemical maditication treatment,the amount of oxidixing radical increased 2 times and the ratio of carboxyl to hydroxyl increased about 4 times. Furthermore the increation of polarity increased the adsorbability to some solate with certain polarity.it yielded notable effection when it used to purify and regenerate solution of non-cyanide galvanizing
