摘要

我们描述了通过将传统染料固定在商业纸张上获得的一次性和廉价的比色装置,称为“捕色器®”(此处以首字母缩略词CC命名),该产品用于防止洗衣机循环中的掉色。这些装置可以用作不同的环境和生物分析物的比色传感器,因为指示剂染料固定在固体材料上,与分析物接触后会改变其光谱特性(颜色和紫外-可见光谱)。分析物含量与每个传感器的uv -可见光谱(或RGB值)变化之间的关系使用化学计量学工具:偏最小二乘回归(PLS)。将这些传感器应用于实际样品时获得了令人满意的结果,因此由于其制备简单,试剂成本低,可以有效地应用于环境和食品分析。

From Colour Catcher® to colorimetric sensors: disposable and cheap devices for inorganic ions determination
We describe disposable and cheap colorimetric devices obtained by fixing classical dyes on the commercial paper sheet known as "Colour Catcher®" (here named under the acronym CC), the product used to prevent color runs in washing machines cycles. These devices can be used as colorimetric sensors for different analytes of environmental and biological interest since the indicator dye, fixed on the solid material, changes its spectral properties (color and hence UV-vis spectrum) upon contact with the analyte. The relationship between the analyte content and the UV-vis spectrum (or RGB values) change of each sensor is provided using a chemometric tool: the Partial Least Squares regression (PLS). Promising results were obtained when applying these sensors to actual samples, so because of their simple preparation with low-cost reagents, they can be effective for application in environmental and food analysis.
