ISO 4317 is a standard that specifies the Karl Fischer method for the determination of water content for the analysis of surfactants and detergents. Surfactants, detergents and some industrial products are critical for their water content because excess water can adversely affect the quality and efficacy of the products.
In particular, this method is used for
It can be applied to cleaning products in powder, paste and solution form. The amount of water in detergents and surfactants should be analyzed for the presence of alkali metal salts.
Karl Fischer titration is an analytical method used to determine water content. This method uses the reaction of iodine (I2) and sulfur dioxide (SO2) to detect the presence of water. Karl Fischer titration is particularly effective in analyzing substances with low water content and allows for very precise measurements.
This titration directly and specifically measures the presence of water. It also gives reliable results even for substances with very low water content, making it an ideal method for many industrial and laboratory applications.
Two titration methods are performed using Karl Fischer reagent:
