| Abstract | ||
| A simple, rapid and sensitive spectrophotometric method for determination of microgram amounts of Resorcinol in aqueous solution and some bulk samples was described.The method is based on a diazotization and coupling reaction between resorcinol and diazotized 4-bromo Methoxy aniline in basic medium to form an intense brown water-soluble dye that is stable, which shows maximum absorption at 448nm. Beer’s law is obeyed over the concentration range of(0.4-4.4) μg.ml-1 of resorcinol , with a molar absorptivity of 2.7844×104 l mol-1 cm-1, and Sandell sensitivity index of 0.0039 μg/cm2 The method does not resort to temperature control or to solvent extraction. The optimum conditions for all colour development are described and proposed methods were successfully applied to the determination of resorcinol in aqueous solution and some bulk samples. | ||
