基于图像比色法的有色溶液浓度检测方法的研究

Study on concentration detection of color solution based on image colorimetric analysis

根据溶液中有色物质颜色值与其浓度成正比的原理,讨论了通过采集样液的图像信息,对溶液中特定显色物质进行定量分析的检测方法。现以测量蓝色硫酸铜溶液为研究对象进行分析,结果表明,该方法测量误差为±5%,且具有实验系统结构简单、造价成本低、线性关系好和灵敏度高等优点。

According the principle that solution color value and its concentration is proportional, a detection method was discussed. Through the acquisition of image information, quantitative analysis of color material can be done. We took the blue CuSO4 as the object for experimental analysis, the results showed that the measurement error is ±5%. The experimental structure is simple, and it is low-cost, a good linear and high sensitivity.
