Determination of Plumbum and Cadmium Migration in Glass Products by Flame Atomic Absorption Spectrometry
Objective:An analytical method for simultaneous determination of plumbum and cadmium migration in glass products by flame atomic absorption spectrometry was established.Method:The glass samples were washed and dried,injected with 4%acetic acid solution,and carried out migration test at 22℃for 24 h.The soaked solution was used for the determination by atomic absorption spectrophotometer.Result:The detection limits of plumbum and cadmium were 0.07 mg·L-1 and 0.007 mg·L-1,respectively.The recoveries of plumbum and cadmium were between 92.0%and 104.5%,and the relative standard deviation was less than 3.82%.Conclusion:The method is simple,accurate and rapid,and is suitable for batch analysis and detection of plumbum and cadmium migration in glass products for food contact.
