紫外分光光度计在丙烯酸阻聚剂含量分析中的应用

The reseacsh of inhibitor content in Acrylic Acid with UV

紫外可见分光光度计在丙烯酸中阻聚剂含量分析中,依据标准GB/T17530.5-1998,能够定量的测出丙烯酸中对苯二酚这类阻聚剂的含量。首先阐述了紫外可见分光光度计的分光光度法的测定原理及其仪器的相关部件,接着介绍了Lambda35型紫外可见分光光度计在丙烯酸中阻聚剂含量分析的应用实例。最后论证了紫外可见分光光度计在丙烯酸阻聚剂含量分析中的应用。

According to the People's Republic of petrochemical industry standard SH/T0166 and SH/T0693-2000, Uv-vis spectrophotometer acrylic acid resistance in the polymerization retarder content analysis, The quantitative measure of acrylic acid can hydroquinone, phenothiazines, hydrogen quinone single methyl ether this kind of resistance of the polymerization retarder content. Firstly, the principle of spectrophotometric determination of the uv-vis spectrophotometer and relevant parts of the instrument are described. Then it introduces Lambda 35 type uv-vis spectrophotometer acrylic acid resistance in the polymerization retarder content analysis of the application example. Finally demonstrates uv-vis spectrophotometer in acrylic acid resistance gather agent content analysis of application.
