In the present work the way of how Calcium, Iron, Sodium, Copper and Cyanide interfere in the analysis of gold by atomic absorption for which two methods used in gold analysis by EAA (Atomic Absorption Spectrophotometry) were taken into account ) and dry analysis; knowing this, it was possible to simulate the real conditions of the analyzes in samples prepared in the laboratory. These samples consist of gold with a known concentration, in addition to the aforementioned pollutants, but always simulating the conditions of the real analyzes to have results of how these "interfering" interfere in the analysis of gold by atomic absorption. For these analyzes the Atomic Absorption Spectrophotometer was used: AAnalyst 300 by Perkin Elmer. As a theoretical framework, a review was made on spectrophotometry since atomic absorption spectroscopy (AAS) is the absorption spectroscopic method used to d...
