Zinc can be determined with this reagent in the presence of Triton X-100, in the pH range 6.20-8.00 with a molar absorptivity of 4.5×104 l/mol/cm Beer's Law was obeyed up to least 1.55 μg/ml. Copper interference was eliminated with a mixture of thiosulfate and ascorbic acid and nickel separated by precipitation with dimethylglyoxime. The proposed method was used for zinc determination in several copper-base alloys and the results of analysis in comparison with certified values indicated that the procedure was accurate and precise. A derivative procedure is also proposed, allowing zinc determination with high sensitivity (5-400 ng/ml).Submitted by Suelen Reis (suelen_suzane@hotmail.com) on 2013-02-18T18:02:01Z No. of bitstreams: 1 Ferreira.pdf: 820345 bytes, checksum: a7be2b9d41efcbd4b7dbefc68394f8dd (MD5)Made available in DSpace on 2013-02-18T18:02:01Z (GMT).
