An emission spectrographic method for the simultaneous determination of trace quantities of copper, manganese, iron, and calcium in various types of dry natural rubber is described. The results are reproducible, the coefficient of variation averaging about 6% for samples of 1 g or larger. Accuracy of this method is verified by parallel analysis with atomic absorption spectrometry.

Abstract The direct introduction of slurries in flow Injection-flame atomic absorption spectroscopy has been studied using a single-channel manifold. The influence of flow Injection parameters on the sensitivity and accuracy of this procedure has been established. A method has been developed for the determination of copper, manganese, and lead In sewage sludge where batch digestion of the samples In a microwave oven is carried out before dilution. Both sensitivity and limit of detection of the flow Injection analysis procedure are adequate for the analysis of actual samples (the limit of detection was 0.06, 0.05, and 0.3 ppm for copper, manganese, and lead, respectively). The accuracy of the proposed method, determined from the analysis of 2 reference samples from the European Community Bureau, is better than that obtained by the continuous aspiration of the samples.
