银瓷杯中银及有害元素的检测研究

Study on detection of silver and harmful elements in silver porcelain cup

银瓷杯作为一种新产品,款式和风格多样,满足了人们的特色需求,得到市场的青睐。实验采用X射线荧光光谱法、ICP光谱法、电位滴定法、显微摄影系统对银瓷杯进行了分析测试和观察。结果表明:银瓷杯因表面银层较薄,X射线荧光光谱法难以获得准确检测结果,可选用电位滴定法进行测试。银瓷杯中常检测到铅,为降低产品中铅含量,建议使用无铅釉料。

As a new product,the silver porcelain cup meets people s characteristic needs and is favored by the market because of its diverse patterns and styles.X-ray fluorescence spectrometry,ICP spectrometry,potentiometric titration,and photomicrography system were used to test and observe the silver porcelain cup in the experiment.The results of the study show that the X-ray fluorescence spectrometry method makes it difficult to obtain accurate detection results due to the thin silver layer on the silver porcelain cup.Potentiometric titration can be opted for detection.Lead is often detected in silver porcelain cups.To reduce the lead content in products,it is recommended to use lead-free glazes.
