【摘要】 开发了紫外分光光度法测定特种溶剂中芳烃含量方法。该方法可以在15分钟内测试出低于1％含量的芳烃。最低检测限1.0×10^-6（m/m）。回收率在94.5％～99.8％,重复性试验RSD=0.29％。该方法对不同生产工艺制得的特种溶剂测试的可靠性有待进一步试验验证。更多还原

【Abstract】 A way for determinating the aromatic in specialty solvents by means of ultraviolet - spec-trophotometry was developed, with which we can detect the concentration of aromatic less than 1% in fifteen minutes. The limit of detection is down to 1 .0×l0-6(m/m) . The relative standard deviation of the method is 0.29% with spiked recoveries of 94.5% -99.8%.The reliability of the method for the specialty sol-vents from different technological processes needs to be verified by furthermore experiments.更多还原
