Determination of Trace Catechol in Waste Water by Kinetic Fluorimetry

QI Wen-juan,CHEN Lan-hua(School of Chemistry and Materials Science,Huaibei Coal Industry Teachers Col lege,235000,Huaibei,Anhui,China)  
A new kinetic fluorimetry method has been proposed for the determinat ion of trace catechol.It is based on the activation effect of catechol on the c atalytic oxidation reaction of acridine yellow by potassium bromate in the prese nce of vanadium,which acts as a catalyst in sulfuric acid solution.The optimum kinetic conditions of experimentation have been studied.The fluorescence quenc hing of acridine yellow is determined by fixed time method.The linear range of the determination was 0.005~0.180 μg/mL with detection limit was 0.002 8 μg/m L.The method has been applied to determining catechol in environmental water sa mples,the RSD was from 2.3%to 2.5%,the recovery was from 96.7%to 101.7%.
