A sensitive, rapid, efficient, inexpensive, and easy-to-use vortex-assisted eutectic solvent microextraction process was extended to quantify Ponceau-4R (PN4R) in beverage samples followed by spectrophotometric detection. Here, a green solvent consisting of tetrabutylammonium bromide: n-octanol at a...
