GONZALEZ-RIVERO, Rosa Amalia; RIBALTA-QUESADA, Juan Alberto; RAMIREZ-GONZALEZ, Surey  e  JIMENEZ-PRIETO, Yamell. Quantification of nickel and cobalt in wastewater from a gold mineral processing plant. Rev Cub Quim [online]. 2021, vol.33, n.3, pp. 345-366.  Epub 26-Out-2021. ISSN 2224-5421.

In the present work, the methods for the quantification of nickel and cobalt by atomic absorption spectrometry in wastewater from a gold ore processing plant were verified. Linearity, precision, trueness and detection and quantification limits were evaluated for both methods, proving that they are adequate for the quantifications of these analytes, according to the proposed purposes. The concentrations obtained for the chemical elements in the wastewater samples analyzed were higher than the maximum permissible limits established for the discharge of such water into rivers, reservoirs and hydrogeological zones.

Palavras-chave : wastewater; nickel; cobalt; verification; atomic absorption spectrometry.
