| Abstract: | A high performance liquid chromatographic method is described for the determination of 5-chlorosalicylic, salicylic, 3-chlorosalicylic and 3, 5-dichiorosalicylic acids in 5-chlorosalicylic acid for industrial use. With an ODS column, the mobile phase is water (pH2. 5 with perchloroic acidmethanol (35 : 65v/v) at a flow rate of 1. 0ml/min and UV detection wavelength is at 226nm. The method is simple, rapid, accurate and effective. |
