Determination of lead and cadmium in textile leach solutions using chemical vapour generation atomic absorbtion spectrometry

A simple and rapid method using flow injection cold vapour AAS and hydride generation AAS were described for the determination of cadmium and lead in textiles leach solutions, respectively. The experimental conditions were optimized for the best sensitivities. The detection limits (3 a) in leachate solutions are 0.05 ng/mL for cadmium and 1.0 ng/mL for lead with a precision between 1- 3% RSD. The accuracy of methods were tested using ETAAS as a comparison method and a standard reference material. In both cases, the results were in good agreement at 95% confidence level. Textile products obtained from local markets were leached in artificial sweat solution. The concentrations of cadmium and lead in textile products were found to be below the limit values assigned by Oeko-tex standards.
