Nanosorbents are frequently used in analytical chemistry for their various applications, including extraction and microextraction of synthetic dyes. Synthetic dyes pose a threat to living organisms, particularly humans, due to their worldwide use in a variety of industries. The removal and quantification of synthetic dyes from various matrices is becoming increasingly important. The use of nanosorbents in dispersive solid phase...

Deep eutectic solvents (DESs) are an emerging class of promising green solvents used as an alternative to traditional organic solvents in various scientific fields. The high biodegradability, biocompatibility, eco-friendliness, tunable properties, and presence of active groups in DESs make them the preferred solvent in a variety of solid- and liquid-phase microextraction techniques. Aside from these benefits, the use of DESs in...

Population expansion, industrialization, urban development, and climate changes increased the water crisis in terms of drinking water availability. Among the various nanomaterials for nanoremediation towards water treatment, FeS-based nanocomposites have emerged as promising candidates in the adsorptive and photocatalytic removal of contaminants. This paper, therefore, evaluates the potential of FeS-based nanocomposites for environmental...

Deep eutectic solvents (DESs) have gained significant attention due to their environmentally friendly properties and versatile applications in various fields, including analytical chemistry. This study investigates the use of a deep eutectic solvent (DES) composed of l-proline protonated with hydrochloric acid and xylitol as a surface modifier for silica-based stationary phases in high-performance liquid chromatography (HPLC)....

Advanced Oxidation Processes (AOPs) have proven to be an effective solution for chemical wastewater treatment, particularly for degradation of organic pollutants, especially dyes. Ozonation is recognized as one of the most prevalent AOPs. Nevertheless, some cases show a lowered efficiency of O3 utilization which is attributed to its inadequate distribution in the treated water causing low residence time, low mass transfer coefficient...
