摘　　要：TiO2掺杂Pd2+作为吸附剂,利用此吸附剂进行了含铬废水的去除试验,并与活性炭吸附法进行了对比,结果表明,对于Cr6+的质量浓度为80mg/L的水样,Cr6+的去除率为99.5%,高于或相当于活性炭吸附法。Cr6+的解析率达到99.6%,吸附剂经再生后可以再行利用。A Pd2+ doped TiO2 adsorbent was used as an adsorbent for the removal of Cr6+ from wastewater while comparison was made with the use of active carbon adsorption method. The results showed that when Cr6+ content in the water sample was 80 mg/L and Pd2+ doped TiO2 adsorbent was used as the adsorbent, the removing efficiency reached 99.5%, which was higher than or equivalent to the efficiency obtained with active carbon as the adsorbent under similar test conditions; while the desorption rate of Cr6+ was 99.6% and the adsorbent was reusable after regenerated.
