GB/T 11912-1989 《Water quality--Determination ofnickel--Flame atomic absorption spectrometric method》 Related products

The GB/T 11912-1989 standard specifies the determination of nickel concentration in industrial wastewater by flame Atomic absirption spectropho-tometry, AAS, which is suitable for industrial wastewater and contaminated environment water samples. The minimum detection concentration is 0.05 mg/L, and the concentration range of calibrated Linear dispersion is 0.2-5 mg/L. Method The absorption of ground nickel atoms on characteristic spectral lines is measured by spraying the test solution into a high temperature flame to determine the nickel content in water. The standard also details the requirements for the required reagents, instruments and equipment.
