Green and simple microextraction method based on deep eutectic solvent-assisted smartphone digital imaging colorimetry (SDIC) for Rhodamine B analysis in food products
{{output}}
This study employed a deep eutectic solvent-based liquid-liquid microextraction method and smartphone digital image colorimetry to detect and quantify Rhodamine B in foods. The deep eutectic solvent, a green solvent, was prepared by mixing tetrabutylammonium b... ...
