| Abstract: | OBJECTIVE:The content of resorcinol in compound resorcinol lotion was determined by dual wavelength specˉtrophotometry.METHODS:Absorbance was determined by using water as the solvent at the wavelength273.5nm and266.1nm.RESULTS:The results showed that the standard curve of resorcinol concentration ranging from20.32μg/ml to60.96μg/ml was in correspondence with Beer’s law.The absorbance difference and the concentration showed a good linear relationship(r=0.9998).The mean recovery of resorcinol was(99.59±0.45)%(n=9).CONCLUSION:This method is simple,quick and acˉcurate. |
