摘要
将邻菲口罗啉吸附负载于６０～８０目活性碳上，制成金属离子富集剂。在ｐＨ＝４时，富集剂对Ｐｂ２＋，Ｃｕ２＋，Ｃｄ２＋，Ｚｎ２＋，Ｃｒ３＋５种金属离子的吸附量分别为４４，２４，１６，１２，１０ｍｇ／ｇ。富集废水中Ｐｂ２＋时的加标回收率为８７％～９１％。
The activated carbon(60-80 mesh) is coated with pnenanthroline to prepare the adsorbent for heavy metallic ions.The adsorption capacity (mg/g) of the adsorbent at pH=4 for Pb^2+,Cu^2+,Cd^2+,Zn^2+ and Cr^3+ are 44,24,16,12 and 10 respectively.And the adsorbent is used to adsorb Pb^2+ in waste water and the recovery is 87%-91%.
