Objective To revise CB/T 5009. 62-2003 and provide technical support for the revision of GB13121- 1991 Hygienic .standardfor ceramicfood containers. Method It is suggested to keep flame atomic absorption spectrometry ( FAAS) in, remove dithizone colorimetry (DSMP) from, add inductively coupled plasma mass spectroruetry (ICP-MS) and graphite furnace atomic absorption spectrometry ( GFAAS) to the latest edition of GB/T 5009. 62. The de.tecting conditions and technical parameters for ICP-MS and CJFAAS were optimized through researches on methodology and inter- laboratory comparison. Results The migration of lead and cadmium from ceramic food containers were detected by ICP-MS and GFAAS. The limit of quantitation ( LOQ) of lead was l. 0 μg/L ( as ICP-MS) and 2. 5μgL ( as GFAAS) , and the LOQ of cadmium was 0. IμgL ( both ICP-MS and GFAAS). The recovery rate of adding standards of lead rates were 89. 0% -1140-/o ( as ICP-MS) and 88. 2c/o -110% ( as GFAAS) , and the recovery rates of adding standards of cadmium were 86. 2% -94. 0% ( as ICP-MS) and 90. 0% -108% ( as CFAAS) in the inter-laboratory. The migration of lead and cadruium from 60 ceramic food container samples produced from different origins were tested by ICP-MS and (;FAAS, no statistically significant differences between these two methods were observed by paired t-test. Conclusion ICP-MS and CFAAS are the most advanced analytical technology with high sensitivity and acc:uracy in detecting trace amount of lead and cadmium. The migration of many trace metals released from ceramic surface could be detected at the same time by ICP-MS. As the GB/T 13121 is going to be revised, more stringent limits for the migration of lead and cadmium from products made by different technologies might be stipulated. Introducing ICP-MS and GFAAS to GB/T 5009. 62 is necessary.
