Determination of lead and cadmium in tea by graphite furnace atomic absorption

Lead and cadmium were determined in the presence of matrix modifiers. Under the optimal measure conditions, lead and cadmium in tea showed excellent linearities with correlation coefficients of 0.9996 and 0.9993 after digestion of tea with HNO3/HCl (3:1, v/v). The recoveries were 94–102% and 91–103%...

description Lead and cadmium were determined in the presence of matrix modifiers. Under the optimal measure conditions, lead and cadmium in tea showed excellent linearities with correlation coefficients of 0.9996 and 0.9993 after digestion of tea with HNO3/HCl (3:1, v/v). The recoveries were 94–102% and 91–103% and RSD values were 8.86% and 13.1%, respectively.
