GB/T 6366-2012 《Surface active agents - Determination of mineral sulfate content - Titrimetric method》 Related products

GB/T 6366-2012 Using the Titrimetric method to determine the content of inorganic sulfate in surfactants, it is suitable for various surfactant products. First, the surfactant Sample Handling is used to convert the inorganic sulfate into a titratable state, and then a suitable titrant is used to react with sulfate ions to calculate the inorganic sulfate content through the amount of titrant. The standard specifies the requirements of Burette and other instruments, and specifies the preparation and calibration of reagents. Detailed description of Sample Handling steps, such as sample dissolving, separation of interfering substances, etc. Standardize the titration operation process, including titration speed and endpoint judgment. According to this standard, the inorganic sulfate content can be accurately determined, which can help surfactant quality control and product performance evaluation.
