In this study, the potential of dispersive surfactant micelle-mediated extraction combined with image colorimetric analysis was assessed for extraction, preconcentration, and determination molybdenum (VI) in environmental samples. approach, cationic cetyltrimethylammonium bromide (CTAB) utilised as a complexing agent, ethanol chosen solvent self-assembly agent. Initially, mixture CTAB is injected into test tube, resulting formation cloudy solution due to dispersion particles aqueous phase. step, coloured ternary complexes obtained from reaction Mo(VI) ions pyrogallol red (PR) presence iodide are extracted by through process. After centrifuging, surfactant-rich phase dissolved 1 mL dimethylformamide (DMF) analysed using smartphone-based self-constructed colorimeter commercial UV-Vis spectrophotometer. mentioned colorimeter, digital final performed based on RGB (Red, Green, Blue) colour model, value R channel used acquire analytical signal. Under optimal conditions, linear range 5–100 μg L−1 limit detection (LOD) 2.1 were achieved colorimeter. Additionally, 15–250 L−1, LOD 3.3 spectrophotometric analysis. Ultimately, proposed method successfully determine various samples, satisfactory recoveries ranging 96 109%.
