TLDR
An analytical method to determine and control the chemical composition andoncentration of a magnesium anodizing solution consisting of three chemicals, sodium dichromate, ammonium bifluoride and phosphoric acid, such as in Chemical Treatment No. 17 of Dow Chemical Company, for example, is presented in this article.Abstract:
An analytical method to determine and control the chemical composition andoncentration of a magnesium anodizing solution consisting of three chemicals, sodium dichromate, ammonium bifluoride and phosphoric acid, such as in Chemical Treatment No. 17 of Dow Chemical Company, for example. Automatic pH titration is used to determine the amount of ammonium bifluoride (NH4 HF2) and phosphoric acid (H3 PO4) concentration at the same time and the concentration of sodium dichromate (Na2 Cr2 O7.2H2 O) is determined separately by the thiosulfate titration technique.read more
