Considering the complex instrumentation and high operator requirements required for the determination of trace lead in zinc oxide produced by direct methods，a simple carrier coprecipitation pre-concentration-xylenol orange spectrophotometric method was proposed.By using strontium chloride as a carrier to precipitate and separate lead in sulfuric acid medium，then converting lead sulfate into lead carbonate with potassium carbonate，dissolving lead carbonate into lead ions with nitric acid and finally forming a purple red complex with xylenol orange，a spectrophotometric method for the determination of trace lead was established.The effects of solution pH，the concentration of chromogenic reagents and the interfering ions on the method were investigated.The results showed that the absorbance value of the generated complex was changed linearly with the concentration of lead ions.The linear concentration range was 1.45~14.49 μmol/L，the linear equation was ΔA=0.059 24c -0.017 15，and the correlation coefficient R2 was 0.990 3.The relative deviation between the measured values of lead in direct zinc oxide obtained by this method and those obtained by atomic absorption spectroscopy was between -1.7% and -1.2%.Compared with the atomic absorption spectroscopy method specified in the current standard GB/T 4372.2—2014 “Direct method for chemical analysis of zinc oxide part 2：Determination of lead oxide content”，this method had the advantages of simple instrument and easy operation，and could be used for industrial promotion.
