Removal of alkali and transition metal ions from water with hydrophobic deep eutectic solvents

Hydrophobic deep eutectic solvents were used for the first time for the removal of metal ions from non-buffered water. It was shown that the extraction occurs via an ion exchange mechanism in which all transition metal ions could be extracted with high distribution coefficients, even for high Co2+ concentrations and low DES/water mass ratios. Maximum extraction efficiency could be reached within 5 s and regeneration was possible.<br/

Low-Transition-Temperature Mixtures (LTTMs) : a new generation of designer solvents

A new generation of designer solvents emerged in the last decade as promising green media for multiple applications, including separation processes: the low-transition-temperature mixtures (LTTMs). They can be prepared by mixing natural high-melting-point starting materials, which form a liquid by hydrogen-bond interactions. Among them, deep-eutectic solvents (DESs) were presented as promising alternatives to conventional ionic liquids (ILs). Some limitations of ILs are overcome by LTTMs, which are cheap and easy to prepare from natural and readily available starting materials, biodegradable, and renewable

New natural renewable low transition temperature mixtures (LTTMs): screening as solvents for lignocellulosic biomass processing

New natural and biorenewable solvents are prepared in this work consisting of high melting temperature starting materials that form low transition temperature mixtures (LTTMs). The physicochemical behaviour of these new solvents can be tailored by a judicious selection of the constituents’ nature and ratio. Their suitability as solvents for lignocellulosic biomass processing is evaluated
