Screening analysis method for harmful element directives in jewelry

National standard GB / T28021 proposes the measurement of harmful elements in jewelry using atomic absorption spectrophotometer (AAS) and inductively coupled plasma emission spectrometer (ICP) for testing, and provides a test solution that can be applied to XRF. The national standard requires a variety of products to be tested, and such products come into direct contact with human skin. There are five categories of representative items. 1: earrings. 2: Necklace, bracelet, bracelet, anklet, ring. 3: watch case, bracelet, buckle. 4: Snaps, buckles, rivets, zippers and metal signs. 5: jewelry, jade, etc.

From the above five types of samples, it can be seen that the first to fourth types are all made of metal materials, which can be precious metal series, steel series or coating series. The fifth category can be attributed to non-metallic series.
According to the national standard GB28480, the content of harmful elements in jewelry should be less than or equal to the maximum limit of the corresponding elements in the table below.

For jewelry or parts that are easily swallowed by children, the content of harmful elements should meet the requirements of the above table, and the dissolution amount should be less than or equal to the maximum limit of the corresponding elements in the table below.

The content of harmful elements in jewelry according to national standard GB / T28020 can be detected by XRF method. After the initial inspection of the X-ray fluorescence spectrometer, we can distinguish between qualified and unqualified products (that is, products whose content is below or above the 30% maximum limit value), but X-fluorescence has a certain range of applications and it cannot be tested. Element valence, so we test the total chromium content in hexavalent chromium. If the total chromium content does not exceed the standard, the amount of hexavalent chromium does not exceed the standard. If the total chromium content is determined by XRF to exceed the standard, you can use an ultraviolet spectrophotometer Quantitative test of hexavalent chromium. However, some suspected products obtained through XRF screening (that is, products whose content fluctuates from the maximum limit and cannot be qualified or unqualified) must be arbitrated by ICP and AAS analysis of destructive testing spectrometers.

In addition, XRF is only a test of the total content of the elements, and it is impossible to detect the amount of dissolution. We can test whether the total amount of elements exceeds the maximum amount of dissolution by XRF. If the maximum amount of dissolution is exceeded, other spectral analysis and detection equipment must be passed (Such as ICP, AAS) to determine whether the dissolved amount of the element exceeds the maximum limit, so if you want to comprehensively solve the harmful element detection solution in jewelry, you ca n’t do it all by XRF alone. You also need to perform other analysis tests. The following figure shows the screening preliminary analysis method for XRF detection of harmful elements in jewelry:
