“…Shaker-assisted liquid−liquid microextraction using hydrophobic DESs was used to remove methylene blue from alkaline solutions (0.5 M NaOH). 34 It was back-extracted into a solution consisting of hydrochloric acid (2 M). The DES used throughout the investigation was decanoic acid with methyltrioctylammonium bromide in a 2:1 molar ratio.…”

Hydrophobic deep eutectic solvents (DESs) are a new generation of water immiscible solvents that have been presented in the literature for the first time in 2015. These solvents have been used for many applications. Here, an overview is given regarding hydrophobic DESs with their physicochemical properties, applications, and the challenges and limitations that the field currently is experiencing. First, a general introduction and an introduction to hydrophobic DESs are presented to explain more about DESs, their origin, and hydrophobic ones. Here, also, an overview of all the hydrophobic DESs presented in the literature is given. After the introduction, physicochemical properties such as density, viscosity, melting point, degradation temperature, volatilities, and solvatochromic properties are discussed. It is continued with the discussion of 21 different applications of hydrophobic DESs. In general, applications related to liquid–liquid extractions, liquid–liquid microextractions, formation of two and three phase systems, removal of components from leaves, gas–liquid extractions, formation of hydrogels, membrane formation, centrifugal partition chromatography, formation of a ferrofluid, coating, photoluminescence, and dye-sensitized solar cells, and catalysis have been investigated. Finally, challenges and limitations of hydrophobic DESs are discussed.

“…For organic pollution, the treatment efficiencies that characterize a tertiary treatment are the accompanying: organic pollution reduction of essentially 95% for BOD, 85% for COD, the nitrogen reduction of essentially 70%, the phosphorus reduction of essentially 80% and the microbiological reduction accomplishing a waste coliform thickness of < 1000 of every 100 ml. Moreover, explicit industrial effluents might require extra treatment for explicit determinants that may not be normal in many wastewaters [18,19].…”

“…Presently, about 82% of lands are polluted by the products of petroleum source (hydrocarbons, solvents etc.) used as an energy foundation in the oil industry, in addition, the chemicals were used in various industries and their wastewaters may be included the different pollutants such as, BTEX, VOCs, mercury, arsenic, nickel and vanadium which was determined by analytical methods [19]. There is a diversity of pollutants influencing water bodies, air, soil and subsoil, such as fuel and oil products, crude oil, hydrocarbon residues, other products resulting from the operation (unsaturated and saturated aliphatic hydrocarbons, and the polycyclic and monocyclic aromatic).…”

Environment pollutants are found here and there in developing countries and these contaminations affect the environment adversely. A few remediation of pollution which includes incineration which is the waste treatment process that involves the combustion of organic substances contained in waste material, the waste handling practices, the recycling resource recovery, the avoidance and reduction methods, the adsorption based on nanotechnology and the bioremediation technology which appears as a cost-effective and environmental friendly approach for cleanup. Recently researches shows that various chemicals (VOCs, BTEX, heavy metals) that might be delivered into the air or water can cause unfriendly health effects which was analyzed based on sample treatments (solid phase extraction: SPE, the liquid-liquid microextraction: LLME, the magnetic solid phase extraction: MSPE) and instruments such as ET-AAS, F-AAS and GC-FID methods. The related weight of disease can be substantial, and interest in research on health effects and intervention in explicit populations and openness circumstances is significant for the development of control systems. Pollution control and determination is thusly a significant segment of disease control, and health experts and analytical chemistry specialists need to foster associations with different areas to recognize and carry out need interventions.

Preparing a sample for analysis is a crucial step of many analytical procedures. The goal of sample preparation is to provide a representative, homogenous sample that is free of interferences and compatible with the intended analytical method. Green approaches to sample preparation require that the consumption of hazardous organic solvents and energy be minimized or even eliminated in the analytical process. While no sample preparation is clearly the most environmentally friendly approach, complete elimination of this step is not always practical. In such cases, the extraction techniques which use low amounts of solvents or no solvents are considered ideal alternatives. This paper presents an overview of green extraction procedures and sample preparation methodologies, briefly introduces their theoretical principles, and describes the recent developments in food, pharmaceutical, environmental and bioanalytical chemistry applications.
