Over the past decade, deep eutectic solvents (DES) have been widely studied and applied
in sample preparation techniques. Until recently, most of the synthesized DES were …

Deep eutectic solvents are compounds formed by a donor and an acceptor of hydrogen
bond; and are in liquid state at ambient temperature. They are non-volatile, with high thermal …

Dispersive liquid-liquid micro-extraction (DLLME) has developed rapidly in recent years
because of its simplicity, miniaturization, cost-effectiveness, easy automation, low …

The worsening damage to the environment caused by chemical production has highlighted
the need for sustainable chemistry. Deep eutectic solvents (DESs) are attracting increasing …

New-generation solvents termed deep eutectic solvents (DESs) are attracting increasing
attention as eco-friendly solvents in analytical chemistry. Recently, a new subclass of DESs …

Lead pollution has increasingly become the focus of environmental pollution, which is a
great harm to the ecological environment and human health. Strict control of the emission of …

Air–assisted liquid–liquid microextraction is a sample preparation method having high
extraction recoveries and enrichment factors with associated low organic solvent …

In this work deep eutectic solvents based on choline chloride and different hydrogen bond
donors were systematically investigated for separation of singly-and multiply-charged metals …

Deep eutectic solvents (DESs) have attracted a lot of interest as a green alternative to ionic
liquids and organic solvents in different fields. The DESs are defined as a mixture of two or …

The global e-waste generation is projected to leap tremendously over the following years
due to the fast urbanization and increasing population. Inadequate management and …
