查询词典 coulometry

The constant current coulometry as a primary method is recognized in international. Based on Faraday's law of electrolysis, it has been successfully used to determine purity of arsenic trioxide. The measuring results depend directly on the reliability of measuring physical quantities and fundamental constants expressed in SI units, and do not need a reference material for comparison.
