GB/T 7378-2012 《Surface active agents - Determination of alkalinity - Titrimetric method》 Related products

GB/T 7378-2012 stipulates that the Titrimetric method is used to determine the alkalinity of surfactants, which is suitable for all kinds of surfactant products. The surfactant sample is prepared into a solution, and the alkaline substance in the sample solution is titrated with an acid standard solution, and the alkalinity is calculated according to the amount of the acid standard solution. The standard specifies the specifications of Burette and other instruments, and specifies the preparation method of acid standard solution and other reagents. Detailed description of Sample Handling, including the weighing and dissolving process of the sample. Standardize the titration operation process, such as titration speed control and endpoint Color judgment. According to this standard, the alkalinity of surfactants can be accurately determined, providing key data for its quality control and application.
