Determination of Resorcinol in Water Based on Chemiluminescent System of Ce(Ⅳ)-Resorcinol With Surfactant Sensitization / 环境与健康杂志

ABSTRACT

Objective To establish a new chemiluminescence method for determination of resorcinol in wastewater. Methods In media of acid chemiluminescence reaction of resorcinol with ceriumⅣ in the presence of Tween 40 as enhancer was investigated. A new chemiluminescence method for determination of resorcinol with flow injection technique was developed. Results The linear range for resorcinol was 8.0?10-8～5.0?10-5 mol/L with 6.0?10-8 mol/L detection limit. The relative standard deviation was 3.5% for 5.0?10-6 mol/L resorcinol in 11 parallel measurements. Conclusion This method can used to determine the content of resorcinol in wastewater of laboratory and resorcinol compound solution with satisfactory results.
