INDIRECT DETERMINATION OF MANEB (MANGANESE ETHYLENEBISDITHIOCARBAMATE) IN SOME FOODS BY FLAME ATOMIC ABSORPTION SPECTROMETRY
A simple, sensitive and rapid flame atomic absorption spectrometric (FAAS) method for the indirect determination of maneb in foods was described. Manganese liberated by the decomposition of maneb has been determined by FAAS and the maneb content has been calculated by using stoichiometric relationship between manganese and maneb. The method has been successfully applied to the analysis of water, tomato, wheat grain and commercial drug samples for the determination of maneb. Relative standard deviation and relative error were lower than 4% and the limit of detection was about 2 μg/mL for maneb.
