| Abstract: | It is to use 5-chloro-2-(pyridyl)-1, 3-diaminobenzene spectrophotometric method for determination of cobalt in water. It carried on the thorough research and technology improvements in sample preparation, sample preservation, sample analysis, interference elimination, detection limit and range of measurement, practical sample determination. Method for the determination of water samples after dispelling the detection limit of 0.009 mg/L, after enrichment method for the determination of the detection limit of 4×10-4 mg/L, after removing interference, the recovery was 96%-101%.Surface water, groundwater, domestic sewage and industrial waste water samples of standard addition recovery rate ranges from 92% to 103%. |
