紫外吸收光谱法测定萘磺酸甲醛缩合物的含量

Contents of Naphthalenesulfonic-formaldehyde Condensate Measured with Ultraviolet Ray Absorption Spectral Method

文章研究了利用紫外吸收光谱测定废水中萘磺酸甲醛缩合物含量的新方法。结果表明，在水溶液中萘磺酸甲醛缩合物的最大吸收波长在298nm，对实验数据进行线性回归，列出了回归方程y=0.0146x-0.0037，相关系数R=0.999，标准偏差为0.0023。此法具有操作简便、快速、准确等优点。

The paper researched that the new way of Naphthalenesulfonic-formaldehyde Condensate（NSFC） are deter-mined by ultraviolet ray absorption spectral. It shows that the maximum absorption spectrum of Naphthalenesulfonie-formaldehyde Condensate in aqueous solution was 298 nm. The experimental data had been made linear regression, regression equation is y=0.0146x—0.0037, R=0.999 and standard deviation 0.0023. This method was simple, quick and accurate advantages.
