小波分解用于冷却水和锅炉用水中氯化物的测定

Determination of Chloride Content in Industrial Circulating Cooling Water and Boilet Water by Wavelet Transformation

尝试了在锅炉用水和冷却水氯化物的测定(电位滴定法)GB/T15453-2008[1]中,使用MATLAB小波工具箱函数。实验结果表明,小波分解用于电位滴定终点(化学计量点)的确定是完全可行的,而且和常规的电位滴定确定化学计量点的方法比较,小波分解法快速、简洁、方便。电位滴定小波分解法是对GB/T15453-2008工业循环冷却水和锅炉用水中氯化物的测定方法的补充和发展。

The MATLAB wavelet toolbox function was attempted to be used in by potentionmetric method GB/T15453 -2008 of detecting chloride content in indrstrial circulating cooling water and boiler water. Test result indicated： the titration end -point （stoichiometric point） ascertained by wavelet transformation was viable, and this method was more simple and rapid than routine method of obtaining the titration end - point （ stoichiometric point）. The titration end - point （stoichiometric point） ascertained by wavelet transformation would be a supplement and development for method GB/ T15453 -2008 of detecting chloride content in indrstrial circulating cooling water and boiler water.
