Determination of trace heavy metals in some textile products produced in Turkey

Abstract

The concentrations of trace heavy metals in textile samples collected from Tokat, Turkey, were determined by flame and/or graphite furnace atomic absorption spectrometry after microwave digestion. The relative standard deviations for the determinations were found to be lower than 10 %. The concentrations of trace metals in analyzed textile samples were found to be in the range of 0.76-341 µg g^-1 for Cu, 0.10-0.25 µg g^-1 for Cd, 0.63-4.84 µg g^-1 for Zn, 1.02-2.50 µg g^-1 for Mn, 3.55-34.3 µg g^-1 for Fe, and 1.20-4.69 µg g^-1 for Ni, respectively. Copper and cadmium contents in textile products analyzed were found to be higher than limit values given by Oeko-Tex. The results of the present work for textile products are compared with literature values.
