ABSTRACT Recent concern about the impact of environmental preservation and health living beings has opened new avenues for scientific research. In this context, contemporary analytical chemistry been marked by development green methodologies, which aim to reduce use toxic reagents minimize processes. Progress in area involves optimization sample preparation techniques functional materials, contribute a more sustainable efficient analysis. Among these miniaturized stand out, as they smaller volumes solvents offer high sensitivity selectivity. The advanced such molecularly imprinted polymers, MOFs, conductive driven innovation procedures regarding complex matrices, including environmental, food, biological samples. These materials selectivity stability, improving efficiency extraction detection specific analytes. This review explores integration methodologies. It critically highlights applications evaluates them using Analytical Greenness Metric Sample Preparation, based on publications from past 6 years.

Unpacking Phthalates from Obscurity in the Environment

Molecules, Год журнала: 2023, Номер 29(1), С. 106 - 106

Опубликована: Дек. 23, 2023

Phthalates (PAEs) are a group of synthetic esters phthalic acid compounds mostly used as plasticizers in plastic materials but widely applied most industries and products. As materials, they not chemically bound to the polymeric matrix easily leach out. Logically, PAEs should be prevalent environment, their prevalence, transport, fate, effects have been largely unknown until recently. This has attributed, inter alia, lack standardized analytical procedures for identifying them complex matrices. Nevertheless, current advancements techniques facilitate understanding environment. It is now known that can potentially impact ecological human health adversely, leading categorization endocrine-disrupting chemicals, carcinogenic, liver- kidney-failure-causing agents, which landed among contaminants emerging concern (CECs). Thus, this review article reports discusses developments PAEs’ standard methods, facilitating emergence from obscurity. further explores opportunities, challenges, limits advancements.

Thermo‐Assisted Deep Eutectic Solvent Based on Dispersive Liquid‐Liquid Microextraction for Preconcentration of Phthalate Esters in Water Samples and Determination by Gas Chromatography With Flame Ionization Detection

Journal of Separation Science, Год журнала: 2024, Номер 47(18)

Опубликована: Сен. 1, 2024

ABSTRACT A thermo‐assisted deep eutectic solvent (DES) based on dispersive liquid‐liquid microextraction followed by gas chromatography with flame ionization detection was developed for the analysis of five phthalate esters in different water samples. In procedure involved, a DES composed lidocaine, an amphiphilic amine, and oleic acid, mixed sample assisted ultrasound, phase separation achieved increasing temperature. The heating extraction system induced change acid‐base properties components. Thus, formation microdroplets provided, two phases were separated. structure upper hydrophobic layer characterized Fourier‐transform infrared spectroscopy. Also, amount analyzed mass spectrometer Karl Fischer titration. Some critical variables yield assessed. proposed method 1.2–1.3 4.1–4.3 µg/L limits quantification, respectively. intra‐day inter‐day percentage relative standard deviations ( n = 5) determined to be range 4.2–6.2% 5.1–7.2%, Ultimately, this samples high recoveries.
