A simple high-performance liquid chromatographic method is described for the determination of Rhodamine B (RB), Erio Acid Red (EAR) and Automate Red B (ARB) dyes which are used as tracers in forestry spray formulations. The dye solutions were analysed at 30oC by reversed phase chromatography on an HP:RP-8, 10 μm MOS Hypersil column using a mobile phase of methanol and water at a flow rate of 1.0 mL/min. Responses were linear over the concentration range of 0.1 to 10 μg/mL for RB and EAR, whereas the range was 1.0 to 10 μg/mL for ARB. The limits of detection were 0.1 μg/mL for RB and EAR, and 1 μg/mL for ARB. The method was successfully used to quantify RB and EAR present in two aqueous formulations of fenitrothion insecticide. However, interference peaks were observed with the oil-based formulation and prevented the quantification of ARB present. |
