摘　　要：采用高温压力罐,将陶瓷和玻璃样品用硝酸-氟硼酸-过氧化氢溶解后,用ICP-AES同时测定电子产品中陶瓷和玻璃里的铅、镉、铬和汞,方法的检测限为0.0015￣0.012μg/mL,方法的回收率和精密度分别为90.4%￣94.4%和0.12%￣4.60%,结果较为满意。该方法快速简便,可应用于陶瓷中的铅、镉、铬和汞日常检验。The ceramics and glass samples from electronic and electrical equipment were digested under pressure with nitric acid,and tetrafluoroborate solution and hydrogen peroxide in a tightly sealed PTFE vessel which was then put into the corrosion resisting steel pressure dissolution can by heating at 180℃ for 4h. The method for the determination of Pb, Cd, Cr, Hg in ceramics and glass have been developed by ICP-AES. The detection limits of the method are in the range of 0.0015＂0.012μg/mL. The recovery rates and precision of the method are in the range of 90.4%-94.4% and 0.12%-4.60% respectively. The method is simple and rapidly with satisfactory results. It will be of practical significance in spectral analysis of ceramics and glass from electronic and electrical equipment daily inspection.
