- Scope
- This method is suitable for the determination of polycarboxylic acid electrolytes such as polyacrylic acid and polymaleic acid in circulating cooling water and natural water, and their content is greater than 1ppm. This method is measured by the turbidimetric method when benzalkonium chloride (dodecyldimethylbenzyl ammonium chloride) and polycarboxylic acid electrolytes such as polyacrylic acid produce ionic association precipitation at pH=8. The content of trace amounts of polycarboxylic acid electrolytes such as polyacrylic acid in water.
