Resumo

RECOVERING PROCEDURES FOR LIQUID AND SOLID Ag RESIDUES.A simple procedure for recovering Ag, generated as residual solutions, from three different analytical methods, is presented.Based on the rate of the total Ag mass recovered, to the initial one in the initial residual solutions, efficiency as high as 97,9 ± 2,9% was obtained in the process.The purity of Ag, as Ag 2 O, was verified by employing this reagent in the determination of S in plant tissue.This leads to the generation of a solid metallic Ag as waste.In this situation, an 88,7 ± 0,6% Ag recovery was acquired, when a HNO 3 solution was employed as solvent.
