摘　　要：采用导《分光光度法研究了对甲苯磺酸痕量组分的测定方法，并选择了求导阶数、农导波长间距等最佳条件。结果证明，导数分光光反法对痕量组分的测定是十分有效的。P-methylbenzensulforate trace components were determined by derivative spectrophotometer and optimum derivative order and wavelength intervals were selected. It is tested that derivative spectrophotometer is very effective for determining trace components.

关 键 词：导数分光光度法 紫外分光光度法 痕量对甲苯磺酸
