Determination of the concentration of cadmium in a Colombian chocolate with 65% of cocoa, and foreign chocolates with different cocoa percentages
the presence of cadmium was evaluated qualitatively and quantitatively in a dark chocolate with 65% cocoa produced in Colombia, and foreign chocolates with different percentages of cocoa. 0.5 grams were taken for the preparation of the samples, and an acid digestion with concentrated nitric acid (HN...
