DETERMINAÇÃO DE METAIS POR TÉCNICAS DE ESPECTROMETRIA ATÔMICA EM AMOSTRAS DE CARVÃO MINERAL E CINZAS UTILIZANDO METODOLOGIA DE SUPERFÍCIE DE RESPOSTA
This paper describes the method optimization using response surface methodology for Cu, Fe, Zn and Na determinations in coal and ash samples by spectrometry techniques. The sample preparation was performed using a recirculation system adapted in the digestion tubes. This system allowed increase of t...
