【 摘 要 】

A spectrophotometricmethod based on the formation of ion-pair complex between haloperidol and eriochromeblack T (EBT) at pH 1.85 has been described. The formed complex was extractedquantitatively into chloroform and measured at 510 nm. Infra red (IR) studieswere performed to confirm the formation of ion-pair complex. Beer's law wasobeyed in the concentration range of 2.0-9.0 µg mL-1 with molarabsorptivity of 2.67 × 104 L mol-1 cm-1.The detection limit was found to be 0.18 µg mL-1. Statisticalcomparison of the results of the proposed method with those of the referencemethod shows excellent agreement and indicates no significant difference inaccuracy and precision.
