通过吸附剂对铜离子的吸附,会使铜离子被”固定“在吸附剂的巯基活性位点上。然后通过滴加过量的S2-会生成微纳米硫化铜,利用硫化铜不溶于水的特性,它会均匀分布在吸附剂空隙中(内部)。从另一方面讲,该方法实现了水溶液中铜(II)的去除,并通过上述工艺同时完成了吸附剂的制备。
The copper ion was affixed to the sulfhydryl active site of an absorbent via the adsorption of the copper ion to the absorbent . Then, excess S2 was introduced to form micrometer or nanomter CuS. The obtained CuS was evenly distributed within the pores of the adsorbent, as the CuS is insolube in water. In another aspect, copper (II) was removed from the aqueous solution by this process, which sucessfully prepared the (Cu loaded) adsorbent at the same time. |
