FIELD: chemistry.SUBSTANCE: microbiological pollution of water is detected. According to claimed method samples with different concentration of colony-forming units (CFU) of bacteria are applied. At stimulation with ultraviolet radiation intensity of fluorescence Iof each sample, as well as intensity of fluorescence Iof control sample, which contains distillated water at wave length λ= 415±10 nm is determined. Then calibrating curve of dependence between CFU and value I-Iin each sample is built, fluorescence Iof analysed sample and value I-Iare determined, corresponding I-Iconcentration of CFUin analysed sample is determined by calibrating curve. In case if CFUis higher than allowable value by more than given value, microbiological pollution is evaluated as dangerous.EFFECT: accuracy of evaluation of infectious danger of water, simplification and reduction of determination time.2 dwg, 2 ex |
