Inductively Coupled Plasma Manganese Molybdenum Validation Zinc A method to accurately determine and quantify manganese, molybdenum and zinc using Optical Emission Spectroscopy-Inductively Coupled Plasma by optical emission spectrometer was optimized and validated. Selectivity/specificity, linearity, repeatability, intermediate precision and bias using reference materials and certified matrix reference material, respectively, were determined. Selected wavelengths (nm) Zn 213.857; Mn 257.610 and Mo 202.031 made it possible to discriminate spectral interferences. Linearity was proved by ad hoc statistical evaluations. Intermediate precision ranged between 5 and 11% and bias was never greater than 12%. Quantification limits (mg/L) were: Mn: 5; Zn: 10 y Mo: 10. Uncertainties associated to analytical determinations ranged between 10% and 16%. The validation of the proposed method demonstrated that it is selective, it provides adequate uncertainties and it is useful to quantify quickly and accurately the studied trace metals in matrices that can be taken intoaqueous solution with prior digestion in acid medium.
