多波长数据线性回归光度法同时测定痕量钼和钛

Simultaneous Spectrophotometric Determination of Molybdenum and Titanium by Use of Linear Regression Analysis

    摘要
  • 摘要: 多波长数据线性回归分光光度同时测定两个相互干扰的组分,具有简便、快速等特点,已用于Mn和Zn、Be和Al、Mo和W以及Fe和A1等体系。本文在文献的基础上,探讨了不同波长下,Mo和Ti与苯基荧光酮络合物的摩尔吸光系数的差异,在520～540nm范围内,选择了10个波长测量吸光度,以数据线性回归法的原理,不经分

     

    Abstract: Mo and Ti are allowed to form complexes with PF-Triton X-100 at pH 1. 2~1. 6(HC1-KC1 buffer). Ascorbic acid and CyDTA are added to mask interfering elements. The absorbance of the mixture is measured at 10 wavelength steps over the range 520-540 nm. The c
