摘　　要：根据《水质分析大全》应用接触法 -砷铈氧化还原法 ,采用 WFZ80 0 - D3A型单光束紫外 /可见分光光度计 ,D3D型打印机 ,代替以往 72 1型分光光度计 ,利用仪器计算机系统通过线性回归处理 ,直接得到水碘含量 (μg/ L) ,优于以往的测定出水样吸光度 (A)值再用计算器通过指数回归计算水碘含量的方法 ,该方法简便、快速 。According to WATER QUALITY ANALYSIS GENERALIZATION, applied the contact method Arsenic Cerium oxidation reduction method and WFZ800 D 3A ultraviolet/visible light spectrophotometric of simple light beam and D 3D typer instead of the traditional 721 spectrophotometric, the water iodine content would be obtained directly by the computer system of instrument and the treatment of linear regression. That is better than the traditional calculating method of water iodine content obtained by the determination of absorption photometric (A) values with the instrument, and then by the index regression with the computer. The method is simple and convenient and high speed, especially suitable for the analysis of many a sample.
