Abstract

In this paper, a method for determination of thiodicarb by reversed-phase high performance liquid chromatography (RP-HPLC) is presented. Analysis was performed on a 250 mm x 4.6 mm i.d. octadecylsilica (ODS or C18) bonded phase column in 8 minutes. Methanol/water mobile phase was used. Ultraviolet detector was used for detection at 232 nm wavelength. The internal standard method (using dimethyl phthalate as the internal standard) was employed. The linearity of the method was verified. The relative standard deviation (RSD) of determination for 75% thiodicarb wetted-powder was 0.18%. The average recovery was 99.89%. The method has been used for analysis of pesticide products and control of production.
