    摘要:

    传统的高锰酸钾消耗量(COD)实验方法是多年来使用较广泛的检测方法,以其实验原理及操作简单、实验成本低被应用于食品接触材料及制品的检测中。但传统的COD实验方法在应对大量待测样品时有检测效率低、人力成本投入大等劣势。近年来出现了一些基于电位滴定的COD自动滴定仪,但该类型的COD自动滴定仪与传统的COD实验方法在原理上有本质不同。而基于颜色识别技术的COD自动测定仪在保持与传统实验方法原理相同的情况下,可代替人工,且在技术指标上满足实验要求,实现自动化,提高检测效率。介绍一种基于颜色识别技术的COD自动测定仪,并通过实验数据对自动滴定仪进行改进优化。

    Abstract:

    The traditional potassium permanganate consumption (COD) test method is the detection method which has been widely used for many years. It has been applied to the detection of food contact materials and its products because it has some advantages, such as experimental operation, simple experimental principle and low experimental cost. But when dealing with a large number of samples, the traditional COD test method seems to be not very well. The traditional COD test method has some big disadvantages, such as low detection efficiency and high manpower cost investment. Therefore, some COD automatic titrators based on potentiometric titration technology have been invented in recent years. However, this type of COD automatic titrator is fundamentally different from the traditional COD test method in principle. The COD automatic measuring instrument based on color recognition technology can replace manual work while maintaining the same principle with the traditional COD test method, meeting the test requirements on technical indicators, realizing automation and improving the detection efficiency. This paper introduces a kind of COD automatic measuring instrument based on color recognition technology, and improves and optimizes the automatic titrator by experimental data.
