Abstract:
Objective To establish a new spectrophotometry for determination of trace resorcin. Methods Resorcin can inhibit discolouring reaction of bromophenol red induced by H2O2 ,which is catalyzed by Fe(Ⅲ) in NH3-NH4Cl medium. Results The detection limit of this method was 0.054 ?g/ml, linear range was 0.16-2.6 ?g/ml, the optimum reaction temperature was 75℃ and the optimum reaction time was 4 min. Conclusion The present method is simple, accurate and can be used to determine trace resorcin in waste water.
