Abstract: |
The nickel content in electroplating waste was determined by Sodium peroxide decomposition sample, hydrochloric acid leaching and inductively coupled plasma atomic emission spectrometry. Determination range: ω (Ni): 0.50% ~ 10.00%. In this paper, an inductively coupled plasma atomic emission spectrometry (ICP-AES) [1] method for determination of nickel content in electroplating waste has been established by using Sodium peroxide alkali fusion, through sample melting time and temperature, instrument conditions, interference experiments of coexisting elements, etc. The method can completely meet the inspection work of nickel content in such materials. The recovery rate of nickel is 92%~105%(n=3) through the standard addition recovery experiment. The method is accurate and simple, and is suitable for nickel determination of electroplating waste. |
