Ultrasound-assisted d-SPE of Fast Green FCF on chitin bio-adsorbent prior to spectrophotometric determination

Abstract

A novel technique called ultrasound-assisted d–SPE developed that based on the adsorption of FCF dye onto commercial chitin. The Fast Green FCF dye's concentration was measured at 624 nm using a UV-visible spectrophotometer. Analyte concentration, solution pH, ultrasound time, and interfering ions—all crucial elements of ultrasound-assisted dispersive solid-phase extraction—were examined and optimized. These findings demonstrated that the developed approach is easy to use, affordable, time-efficient, dependable, and suitable for a wide range of water samples. This novel method demonstrates significant potential as a viable alternative to existing removal techniques, particularly in applications related to dye removal.
