Objective: To establish a spectrophotometric method for the determination of the color of cefoperazone sodium and sulbactam sodium for injection. Methods: The difference of absorbance value at 440 nm and 550 nm was used to determine the color of cefoperazone sodium and sulbactam sodium for injection. Results: Spectrophotometric determination of the results more intuitive and accurate. Conclusion: This method can be used as injection of cefoperazone sodium and sulbactam sodium color inspection method.
