Objective This study aims to establish an efficient andaccurate method for the determination of zinc content in mineral samplesbased on the flame absorption method of atomic absorptionspectrophotometer, in order to meet the growing demand for metal elementdetection in various fields. Methods The zinc content was determined byatomic absorption spectrophotometer, combined with pretreatment samples,experimental procedure, optimization of instrument measurementconditions and establishment of standard curve. Results The establishedmethod has high precision and accuracy, the recovery rate is99.1%~99.9%, and the correlation coefficient is 0.9998 . The detectionlimit of the method was ${0.1}\mathrm{{\mug}}/\mathrm{{mL}}$ , indicating that the method had goodquantitative analysis ability. Conclusion The method has not only highsensitivity and selectivity, but also simple operation and reliableresults, which is of great significance for environmental protection andoptimal utilization of resources.
