INDIRECT DETERMINATION OF MANEB (MANGANESE ETHYLENEBISDITHIOCARBAMATE) IN SOME FOODS BY FLAME ATOMIC ABSORPTION SPECTROMETRY

Abstract

ABSTRACT

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.

BAZI GIDALARDA MANEBİN (MANGAN ETİLENBİSDİTİYOKARBAMAT) ALEVLİ ATOMİK ABSORPSİYON SPETROMETRİ İLE DOLAYLI TAYİNİ

Abstract

Gıdalarda manebin dolaylı tayini için basit, duyarlı ve hızlı bir alevli atomik absorpsiyon spektrometrik (FAAS) yöntem açıklanmıştır. Manebin bozunmasıyla açığa çıkan mangan FAAS ile tayin edilmiş ve mangan ve maneb arasındaki stokiyometrik ilişkiden yararlanarak maneb içeriği hesaplanmıştır. Önerilen yöntem, maneb tayini için su, domates, buğday ve ticari ilaç numunelerine başarıyla uygulanmıştır. Bağıl standart sapma ve bağıl hata %4’ten daha küçük ve maneb için gözlenebilme sınırı yaklaşık 2 µg/mL’dir
