水中丙烯腈含量分析方法研究

On analysis method of acrylonitrile content in aqueous solution

为方便、快速、准确地测定水溶液中丙烯腈含量，分别对气相色谱法、折光率法和紫外分光光度法进行了研究。当丙烯腈质量浓度在100mg／L-10000mg／L时，宜采用气相色谱法分析；当质量浓度大于10000mg／L时，可以采用操作简单、分析可靠的折光率法；对于100mg／L以下的痕量丙烯腈分析，宜采用紫外分光光度法。

In order to determine acrylonitrile content in aqueous solution conveniently, rapidly and accurately, the gas chromatography, refractive index method and ultraviolet spectrophotometr are investigated. When concentration of acrylonitrile solution is between 100 mg/L -1000 mg/L, gas chromatography is preferred. When concentration is above 10 000 mg/L, refractive index method should be used with simple operation and reliable analysis. Ultraviolet spectrophotometry should be applied when concentration is less than 100 mg/L.
