PRÉ-CONCENTRAÇÃO BASEADA NA COPRECIPITAÇÃO USANDO CROMATO DE PRATA COMO CARREADOR PARA DETERMINAÇÃO DE COBRE POR FAAS
In the present paper, a preconcentration procedure based in the coprecipitation of copper by silver dichromate (Ag2CrO4) and consecutive determination by flame atomic absorption spectrometry (FAAS) was proposed. The experimental factors were optimized from application of the Doehlert matrix and the...
