Determination of Potash concentration in bronze baths
Potash analysis makes it possible to check the concentration of free hydroxides in bronze baths: the value must be kept within well-defined ranges to ensure an optimal deposition rate and to obtain a deposit free of aesthetic defects.
Monitoring the free potash value is essential on the production line in order to provide real-time correction and prevent defects on the finished product.
Method
Test principle
The free potash value is determined by the reaction between hydroxide ions in the galvanic bath and a chromogen. The optical intensity is proportional to the concentration of hydroxide ions in the analyzed sample.
Calibration curve
The calibration curve was obtained by correlating the CDR method with the reference method.
