APPLICATION OF THE FAST ETAAS METHOD FOR THE DETERMINATION OF CHROMIUM, COBALT AND NICKEL IN SAMPLES OF PRESERVED FOOD

A fast method for tile determination of chromium, cobalt, nickel in pr eserved food is presented. Samples were dried and wet ashed and the el ements in question were determined using atomic absorption spectrometr y with electrothermal atomization (ETAAS) using two temperature progra mmes. The use of the fast temperature programme which omits the ashing of the sample makes possible to shorten three times the analysis time . This method gives correct results when determining Cr, Ni and Co in samples of preserved food.
