METHOD OF DETERMINING MICROAMOUNTS OF TOTAL CHROMIUM IN WATER |
| 摘要 |
FIELD: analytical chemistry, more particularly determination of total chromium ((Cr<SP>III</SP> and Cr<SP>VI</SP>)) in fish breeding water reservoirs. SUBSTANCE: method comprises concentration of chromium buy evaporation and treatment which eliminates effect of impurities which interferes with photometric determination of chromium with respect to reaction with diphenyl carbazine. EFFECT: more efficient determination method. 3 ex
