铬黑T的三乙醇胺—无水乙醇溶液作为络合滴定指示剂稳定性的研究

Study on the Stability of EBT in Triethanolamine and Ethyl Alcohol Solution as an Indicator in Compl

  • 摘要: 本文用络合滴定法和分光光度法对铬黑T在三乙醇胺和无水乙醇溶液中的稳定性进行了研究,认为铬黑T在三乙醇胺和无水乙醇溶液中作为络合滴定指示剂至少在一年内有效。

     

    Abstract: The stability of EBT in triethandamine and ethyl alcohol solution was studied by complexometric titration and spectrophotometry.The results obtained shown that the validity of EBT solution is more than one year.
