Abstract
Chemosensors have attracted increasing attention for their usefulness on-site detection and monitoring. In this study, we elucidated a novel, facile, and highly selective Chemo-Paper-Sensor (CPS) for detection and monitoring of strontium (Sr2+) ions, which means a potent colorimetric sensor based on a Chrysoidine G (CG)-coated paper strip. The CPS for highly selective colorimetric detection of strontium ion was handily analyzed to determine the red-green-blue (RGB) value using portable devices such as desktop digital scanner and mobile phone camera, quantitatively. Interestingly, an orange to dark orange color transition was observed when the aqueous and solid paper colorimetric sensor was introduced to Sr2+ ion, respectively. It was demonstrated that the value of the signal has a linear relationship with concentrations of the strontium in the 500Â ppm to 100Â ppb range with a detection limit of 200Â ppb. We believe that a newly developed Chemo-Paper-Sensor will be useful in a wide range of sensing applications.
