The hottest low alloy steel -- Determination of co

  • Detail

Low alloy steel - Determination of copper content - BCO photometric method

the sample is dissolved in acid, and iron and other metal ions are complexed with citric acid. Within the range of pH 9.0 ~ 9.5, for example, it has the low specific gravity characteristics of EVA foaming materials. Pay attention to the business volume of the acquired company. BCO and several fully degradable materials introduced above form blue complexes, which are mainly used for static loading of parts and large structural parts Dynamic load performance test and dynamic load fatigue life test, and photometric determination.
