[Assay of diclofenac sodium and codeine phosphate in tablet by multiwavelength K-factor spectrophotometry].
Assay of diclofenac sodium and codeine phosphate in tablet is reported in this paper. The calibration curves were linear over the range of 11.18-25.40 microg/mL of diclofenac sodium and over the range of 6.785-15.42 microg/mL of codeine phosphate. The average recoveries and relative standard deviations of diclofenac sodium and codeine phosphate were 100.1%, 0.36% and 100.7%, 0.80%, respectively. The method is simple and rapid, and the results are satisfactory.
