文摘
A method for sequential determination of Cd and Pb by HR-CS GF AAS was proposed. The method allows the determination of Cd and Pb in pharmaceutical formulations. The use of the primary lines allowed a method with low limits of quantification. A single injection of a sample solution allows the determination of two elements. A single heating program was established for quantification of the two metals.
