Simple Deep Eutectic Solvent-Based Liquid Phase Microextraction for Sudan IV from Food, Water, and Cosmetics

Analytical Letters, Journal Year: 2025, Volume and Issue: unknown, P. 1 - 13

Published: Jan. 3, 2025

An accurate, simple and eco-friendly method was presented by liquid phase microextraction using a deep eutectic solvent (DES) for its preconcentration before performing spectrophotometric analysis of Sudan IV. To extract IV at pH 4.0 prepared mixture tetrabutylammonium bromide 1-octanol in ratio 1:2 used. The factor 62.5 the limit detection 7.5 µg L-1. Addition/recovery tests demonstrated validity method. appears to applicable determining water, food cosmetics samples.

Chinese Herbal Medicine Residue‐Derived Biochar Assisted Matrix Solid Phase Dispersion Microextraction of Synthetic Dyes From Lake Sediments Using Supramolecular Solvents as Dispersing Solvents

Journal of Separation Science, Journal Year: 2025, Volume and Issue: 48(4)

Published: April 1, 2025

ABSTRACT In this study, a new matrix solid‐phase dispersion (MSPD) method was developed and applied to extract auramine O (AO) rhodamine B (RB) from sediment samples. A supramolecular solvent (SUPRAS) composed of hexafluorobutanol (HFB) linaool used as the dispersing MSPD. Biochar, obtained by pyrolysis Chinese medicine residue namely Sophora japonica L., sorbent MSPD procedure. Parameters influencing extraction efficiency including type volume solvent, amount sorbent, grinding period, vortex time were investigated optimized. Under optimized conditions, linear range target analytes 3–400 µg g −1 with correlation coefficients higher than 0.9964. The provided low limits detection quantification, excellent precision (intra‐ inter‐day analysis relative standard deviations below 5.5%). Finally, proposed determine synthetic dyes in Dianchi Lake sediments satisfactory recoveries 93.5%–105.1%, indicating applicability for determination real Compared traditional sample preparation samples, reduced time, sample, organic usage. is easy, fast, green can be various
