摘　　要：利用市面中常见的杜鹃花修剪后的花茎,制备生物质吸附剂,进行吸附试验研究,并探讨碳化前后杜鹃花茎对废水中Cr^(6+)的吸附成效。研究结果显示,碳化后的杜鹃花茎粉末比碳化前的杜鹃花茎粉末能吸附较多Cr^(6+)。利用碳化前杜鹃花茎粉末吸附废水中Cr^(6+),能去除废水中56.25%Cr^(6+);而利用碳化后的杜鹃花茎粉末吸附废水中的Cr^(6+),能去除废水中57.03%Cr^(6+)。Chrome-containing wastewater possess a threat to human health due to its diverse sources and extensive influences.In this study,the pruned stems of rhododendron commonly found in market were used as a biological chrome adsorbent and tested.The adsorption experiments of Cr^(6+) were conducted with both rhododendron stems(before and after carbonization),which include the effects of addition amount,retention time,shock velocity and Cr^(6+) concentration.The results indicate that more Cr^(6+) was adsorbed by the carbonized rhododendron stems than the other.In addition,the untreated rhododendron stem powder could remove 56.25%Cr^(6+) in wastewater,while the carbonized rhododendron stem powder could reach 57.03%removal.
