Abstract

Bu çalışmada, değişik firmalara ait 20 farklı bitkisel sıvı yağda 'aa tomik ab-
“sorpsiyon spektrofotometresiile demir, nikel, bakır ve çinko miktarları tayin edili
Genel olarak analiz edilen yağlarda bakır ve nikel bulunmamiş, demir ve
çinko miktarları ise literatürde verilen üst. sınır değerlerinin çok üstünde bulun
muştur.

Abstract

Determination of 19; Nickel, Copper and Zinc in Vegetable Oils i “Prodüced in Turkey. ina total number of 20 vegetable oils produced by different. firms, the amounis of iron, nickel, copper and zinc were determined by atomic âbsorptlon spectrophotometiy. . » 'The amounts of copper and nickel were. geheraliy at zero level, whereas iron “and zinc concentrations were higher than those of levels given in literature,
