由于向红亚铜灵(2,9-二甲基-4,7-二苯基-1,10-菲啰啉,BC)对铜的选择性极高,故以BC为试剂光度法测定水及废水中微量铜已成为美国国家标准检验方法;作者前文以TritonX-100胶束增溶铜(Ⅰ)-BC,体系应用于海洋生物组织中微量铜的测定,获得了满意结果。以上两种方法的灵敏度均不适于天然水中痕量铜的测定。应用非离子表面活性剂“浊点析相法”测定微量、痕量元素已有报导,但未见应用BC-TritonX-100析相法测定痕量铜的报导,由于析相法的操作不同,其富集的倍数皆不一致。其中称重法的操作不便,富集的倍数亦有限并需要特制的微型比色池:戚文彬等人采
Since copper (23) is highly selective to copper (2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline) BC And trace amounts of copper in wastewater have become the national standard test methods. The authors previously used TritonX-100 micelles to solubilize copper (I) -BC and applied it to the determination of trace copper in marine biological tissues. Satisfactory results were obtained. The sensitivity of the above two methods are not suitable for the determination of trace amounts of copper in natural water. Determination of Trace and Trace Elements by Non-ionic Surfactant “Cloud Point Analysis” has been reported, but no trace copper has been reported by BC-Triton X-100. Due to the different operation of the separation method, The enrichment multiples are inconsistent. The weighing method is inconvenient to operate, the enrichment multiplier is also limited and a special micro-cuvette is needed: Qi Wenbin et al.
