| 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％。

| Abstract: | 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%. |
