GB/T 17832-2008 stipulates the determination of silver content in silver alloy jewelry by the potassium bromide volumetric method. It is suitable for all kinds of silver alloy jewelry products. The method is based on the reaction of silver ions and bromine ions to generate settling, and the reaction endpoint is determined by Potentiometric titration, poten-tiometry, and then the silver content is calculated. The standard specifies the required instruments, such as Potentiometric titrator, etc., and specifies the preparation of reagents. Detailed description of Sample Handling steps, including sample dissolving, etc. Standardized titration operation procedures, such as titrant addition, potential monitoring and endpoint judgment. According to this standard, the silver content in silver alloy jewelry can be accurately determined, providing key data for product mass control and market transactions, and safeguarding consumer rights and interests.
