Comparación bibliográfica de la eficiencia del método de digestión ácida tradicional y asistida por microondas en la preparación de muestras

Abstract

This research compares microwave-assisted acid digestion (DAAM) and Traditional Acid Digestion (DAT) techniques for the preparation of Cu concentrate samples, in order to establish the most efficient technique, through bibliographic collection. The purpose of DAT and DAAM is to dissolve the sample by using oxidizing agents and high temperatures. This establishes the advantages and disadvantages of both techniques and evaluates the results of studies conducted by other Cu quantification authors. The results obtained in the quantification of Cu DAAM the calibration curve presented an R2 value of 0,9971, a % recovery of 99,77% and a CV of 0.72; while for DAT the calibration curve gave a value of 0,9965, a % recovery of 73.76% and a CV of 1.57. Statistical tests determine that there are no significant differences in accuracy, but there are in precision.
