In present days, an important problem is the presence of different pollutants in wastewaters resulted from textile fabrication, especially from the dyeing process. In Romania the textile industry does not solve yet the problem of pollutants in accordance with the norms of European Union. From this reason many research labs from chemical and environmental areas tried many modern methods for monitoring and degradation of pollutants resulted from textile fabrication. So, in this paper bwere used some physical-chemical analyses (pH, UV-VIS, RMN, HPLC, AAS, etc.) and microbiological tests for identification, control and, finally, degradation (if it is possible) of organic and inorganic pollutants resulted bfrom dyeing synthetic fibers with blue bcationic dyes obtained by original synthesis.
