Abstract
The cloud point extraction (CPE) method using mixed micelles is employed to extract and separate erythrosine. Various conditions affecting the separation process were studied, including the amount of hydrochloric acid, temperature, heating time, Co(II) ion concentration, surfactant volume, and the impact of organic solvents on the dissolution behavior of the cloud point layer. The calibration curve was linear for concentrations ranging from 5 to 1000 μg/mL. The proposed methodologies were validated for drug and food analysis. Statistical analysis compared data from the CPE techniques with those from the HPLC method. The AGREE assessment approach was used to evaluate the environmental sustainability of the methods. It indicated that the CPE method adhered more to green characteristics than the HPLC method.
