А selective, sensitive and express extraction-spectrophotometric method %г the determination syurmy with 1 - (2 - pyridylazo) -
2 - naditolom (polyacrylonitrile). The meihod of extraction- spectrophotometric determinaiion of with (polyacrylonitrile) tested
in the analysis оf industrial wastewnter without separaiion of elemenis associated with the reproducihility of 2-5%.
The developed method is recammended for the analysis оf industrial waste wuter, ores, concentrates, rocks and other complex
chemical composition materials.
