摘要
目的建立测定水中的间苯二酚的化学发光新方法。方法在酸性介质中,利用表面活性剂吐温40作为Ce(Ⅳ)-间苯二酚化学发光反应体系的增敏剂,建立了Ce(Ⅳ)-间苯二酚-吐温40化学发光新体系,结合流动注射技术建立测定痕量的间苯二酚化学发光分析法。结果该方法的线性范围为8.0×10-8～5.0×10-5mol/L,检出限为6.0×10-8mol/L,对5.0×10-6mol/L间苯二酚进行11次平行测定,相对标准偏差为3.5%。结论该法可用于实验室废水、复方间苯二酚溶液(Ⅰ)中的间苯二酚含量的测定。
Objective To establish a new chemiluminescence method for determination of resorcinol in wastewater. Methods In media of acid chemiluminescence reaction of resorcinol with ceriumⅣ 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.
