电感耦合高频等离子体(ICP)作为一种新型光源用于测定废水中的微量元素已有许多报导。利用螯合剂将溶液中痕量元素进行选择性吸附、萃取、分离与富集已成为一种有效的方法。本文利用本校合成的带有肟、胺、羧基功能团的螯合纤维素,在pH6的条件下,对溶液中痕量元素镧、钇、铬、钛等的富集、干扰、ICP工作条件以及螯合纤维对待测元素的饱和吸附量等进行了试验,並对废水样进行了分析,获得了良好的结果。
Inductively coupled high-frequency plasma (ICP) as a new light source for the determination of trace elements in wastewater has been reported. Selective adsorption, extraction, separation and enrichment of trace elements in solution using chelating agents have become an effective method. In this paper, the chelated cellulose with oxime, amine and carboxyl functional groups synthesized at our university was used to enrich and disturb the trace elements such as lanthanum, yttrium, chromium and titanium in the solution under the condition of pH6, ICP working conditions and Chelated fiber saturated adsorption amount of the elements to be tested were tested, and the wastewater samples were analyzed and good results were obtained.
