GB/T 4010 Ferroalloy chemical analysis of the sample to take and preparation
3 method summary
Samples by nitric acid and perchloric acid decomposition, in the ammonia medium, with constant current electrolysis, then nickel deposition to the platinum cathode. After electrolysis is terminated,
The platinum cathode was washed with water and absolute ethanol, dried and weighed and cooled. Platinum on the cathode of cobalt, copper, iron, zinc, manganese and other impurities, electrolytic residue and
The residual nickel, cobalt, copper, iron, zinc and manganese contents in the filter residue were measured by inductively coupled plasma atomic emission spectrometry. Finally, calculate the calculation
The total amount of nickel in the sample, and the cobalt, copper, iron, zinc and manganese contents in the sample.
