GB/T 11910-1989 《Water quality--Determination of nickel--Dimethylglyoxime spectrophotometric method》 Related products

This standard specifies the determination of nickel content in industrial wastewater and nickel-contaminated environment water using the diketoxime Spectrophotometric method, spectrophotometry. The method is to form a burgundy complex of nickel and diketoxime and perform spectrophotometric determination at 530 nm wavelength. The measurement range is 0.25 to 10 mg/L, and the measurement range can be extended by adjusting the sample volume or diluting it appropriately. This standard applies to the determination of nickel content in water quality analysis.
