Abstract

This work presents the results of the work on the determination of a pollutant in a model solution, the antibiotic cefotaxime, using the spectrophotometric method. In several series of experiments, the minimum concentrations of cefotaxime in model solutions that can be detected with a spectrophotometer PE-5400 UV were established; a feature of cefotaxime was revealed - the increase of the optical density peak in the samples when the pH is shifted to an acidic environment, especially at pH values from 0.2 to 2.0. The obtained values of optical density and absorption spectra of the model solution of cefotaxime can be used when a technique for the detection of antibiotics in various media, including urban wastewater.

模型溶液中污染物浓度的测量

本文介绍了用分光光度法测定抗生素头孢噻肟模型溶液中污染物的结果。通过一系列实验，建立了PE-5400紫外分光光度计可以检测到的模型溶液中头孢噻肟的最低浓度;揭示了头孢噻肟的一个特征——当pH值在0.2 ~ 2.0之间变化时，样品的光密度峰增加。所获得的头孢噻肟模型溶液的光密度和吸收光谱值可用于各种介质(包括城市废水)中抗生素的检测技术。
