Lithium, declared critical raw material by the European Union in 2020, is a competitor to hydrogen as alternative petroleum. Its use increasing while reserves are declining, boosting new sources, seawater desalination concentrates. In this work, computational study of most promising extractants, β-diketones and organophosphates combinations thereof, towards lithium presence metal ions found con...

Introduction . Natural deep eutectic solvents (DESs) are promising extractants for many biologically active substances from plant raw materials. They biodegradable, safe, stable, their production is affordable and easily feasible, the extraction efficiency comparable to known organic solvents. In this regard, interest in has been steadily growing recent years, they being used various fields of ...

The aim of this investigation was to determine the occurrence of As, Cu, Cr and Zn in the soil at an abandoned wood preservation unit and to examine some possible extractants for the contaminants in the soil. The mean As content of the contaminated surface soils (0-10 cm) was 186 mg kg(-1), where as the mean concentrations of Cu, Cr and Zn in soils from the contaminated area were 26, 29 and 91 ...
