Determination of iron and manganese in tea samples by flame atomic absorption spectroscopy

Tea samples, marketed by different companies through out the country, have been collected end analyzed for inn end manganese by flame atomic absorptio n spsectroscopy. Dry ashing well as wet procedures were employed for decomp osing the tea samples and results obtained san both the procedures were com pared The average amount of iron, estimated in thirty samples, war 9.38 ppm while that of managanese was found 175 ppm. For both metals relatively hig her results were obtained when samples wan decomposed with sulphuric acid a nd hydrogen peroxide.
