Measurement of pollutant concentration in the model solution

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