Elimination of matrix effect in quantitative analysis of elements using x-ray fluorescence
Description
The emission-transmission method of Leroux and Mahmud, an experimental technique for compensating matrix effects in photon excited X-ray fluorescence analysis, was used to determine the concentration of lead and antimony in pellets of galalith. The effect of interfering elements was studied by adding various concentrations of mercury and tin to the respective pellets. To illustrate possible environmental applications, a number of pellets was prepared from leaves of almond trees located in different regions of Rio de Janeiro. Lead concentrations were determined for the dried leaf material and showed values ranging from 50 to 145 parts per million

O metodo experimental da emissao-transmissao de Leroux e Mahmud, o qual corrige efeitos de matriz na analise pela fluorescencia de raios X, e utilizado para determinar quantitativamente, concentracoes de chumbo e antimonio em pastilhas de galalite. A influencia de concentracoes diferentes de mercurio e estanho adicionados a pastilha, sobre o chumbo e antimonio respectivamente, foi estudada. Como aplicacao a poluicao, a analise quantitativa de chumbo em pastilhas feitas de folhas de amendoeira secas, colhidas em diversos bairros do Rio de Janeiro, tambem foi feita, encontrando-se concentracoes variando desde 50 ate 145 partes por milhaoFiles
