Objective: To establish a method for the determination of the trace zinc in compound sodium selenite eye drops. Methods: Xinshiji Spectrophotometry was applied (detective wavelength 619 nm). Results: The detected concentration was good linear relationship with its absorbance (r=0.9999) within the range of 1.14-6.84 μg·mL-1 for zinc sulfate,The average recovery of the three concentrations (high,medium and low) was 99.9%,100.0%,100.1% with RSD 0.83%,0.64%,0.81% (n=9). Conclusion: The method was simple,quick and accurate for the determination of trace zinc in compound sodium selenite eye drops.
