Determinação simultânea de As, Cd e Pb em amostras de água purificada para hemodiálise por espectrometria de absorção atômica com forno de grafite, após otimização multivariada baseada no uso de planejamento experimental
Abstract:Recebido em 19/12/06; aceito em 30/11/07; publicado na web em 24/7/08 SIMULTANEOUS DETERMINATION OF ARSENIC, CADMIUM AND LEAD BY GF AAS IN PURIFIED WATER SAMPLES FOR HEMODIALYSIS AFTER MULTIVARIATE OPTIMIZATION BASED ON FACTORIAL DESIGN. This paper reports the development of a methodology for simultaneously determining As, Cd and Pb, employing GF AAS with polarized Zeeman-effect background correction. In order to make the procedure applicable, the influence of pyrolysis and atomization temperatures and the amo… Show more
