合成了新试剂二安替比林对羟基苯乙烯基甲烷(DApHVM),并研究了其和格(Ⅵ)的显色反应,在磷酸介质中,Mh(Ⅱ)存在下,DApHVM在室温下和铬(Ⅵ)生成红色产物, λmax= 540 nm,ε= 1.76 x106L·mol-1·cm-1,铬(Ⅵ)含量在 0~ 30μg/L内符合比尔定律,方法用于环境水样中铬(Ⅵ)的测定,结果令人满意。
A new reagent, DApHVM, was synthesized and its color reaction was studied. Under the presence of Mh (Ⅱ), the reaction of DApHVM at room temperature Beer ’s law was obeyed for chromium (Ⅵ) when the content of chromium (Ⅵ) was 0 ~ 30μg / L with λmax = 540 nm and ε = 1.76 × 106L · mol-1 · cm- Determination of chromium (Ⅵ), the results are satisfactory.
