摘　　要：采用"整器粉碎法"对陶瓷样品的铅镉溶出量进行检测。对陶瓷样品进行耐酸腐蚀、以及化学组成测试分析,发现样品的酸侵蚀程度不仅与酸的温度、浓度、侵蚀时间有关,还与样品的化学组成,尤其是Ca、Mg的含量有着密切的关系。我国德化等地生产的低温轻质白陶样品相对受酸侵蚀程度较大,打碎后废弃于自然界中,经过较短时间可自然风化降解。It was more effective that ceramicware samples were ground into powder to detect cadmium and lead. With the testing of chemical compositions and acid-resisted experiment it was found that the degree of acid etching to ceramicware was related not only to the concentration of acid,the temperature and time of acid etching,but also to the compostitions of the ceramicware,especially the content of Ca and Mg of the ceramicware. Some kind of ceramicware produced in Dehua can be eroded seriously by acid. It means that this kind of ceramic product can easily degrade in the nature.
