摘要
为实现对纺织生产过程中过氧化氢(HP)浓度的宽量程检测,提升检测精度、效率及其工艺适应性,对现阶段有关HP浓度检测方法及数学模型进行了介绍。阐述了HP浓度6种检测方法:常规滴定法、电化学分析法、分光光度法、荧光/化学发光法、折射率法和微波法,分析了各检测方法工作原理、研究进展及适用性,剖析了相关数学模型。研究发现:常规滴定法虽然精度高但耗时耗力;电化学分析法响应快,抗干扰能力强;分光光度法成本较高,相对复杂;荧光/化学发光法灵敏度高,但干扰较多;折射率和微波法灵敏度高,但目前只能测量单质溶液。经分析得知,电化学分析法比较适用于纺织领域中HP的检测问题,可有效解决高浓度HP所引起的欧姆降问题,是未来HP检测研究重点。
In order to effectively solve problems in the concentration detection of hydrogen peroxide(HP)in textile process,and to improve the accuracy,efficiency and range of the detection,this paper reviewed on the detection method and mathematical model of HP.Six methods for detecting HP concentration were examined,including conventional titration,electrochemical analysis,spectrophotometry,fluorescence/chemiluminescence,refractive index and microwave.The principle,research progress and applicability of each method were analyzed.It is found that although the conventional titration method has high precision,it is more time and energy consuming.Electrochemical analysis has fast response and strong anti-interference ability.The cost of spectrophotometry is high and it is relatively more complicated.Fluorescence/chemiluminescence method has high sensitivity but more shows interference.The refractive index and microwave methods are highly sensitive,but at present they apply only to single component solutions.According to the analysis,electrochemical analysis is deemed to be more suitable for detecting HP in the textile process,and the effective solution to ohmic drop caused by high concentration of HP would be the one of the focuses for future research.
