“…For the decontamination of water sources at drinkable levels, membrane techniques are more appropriate, but these techniques are frequently very expensive, and are preferred for the treatment of limited flow rates with low initial metal concentrations. Extractant impregnation of porous resins has also been investigated for metal removal; the immobilization of the extractant prevents the release and the loss of hazardous and expensive reagents with optimized transfer properties (driven by the porosity of the supports [3][4][5]). This is an intermediary technique between solvent extraction process and sorption on functional resins.…”

The necessity of decontaminating effluents for the dual purpose of environmental beneficiation and valorization of low-grade resources is driving the development of new sorbents. The functionalization of biopolymers is a promising strategy for improving sorption performance. Incorporating magnetic micro-particles offers an opportunity for the facilitated recovery of spent micron-size sorbent. Combining magnetic facilities and biopolymer functionalization represents a winning strategy. Magnetic glycine-grafted chitosan (G@MChs) was synthesized for the sorption of Ni(II), Zn(II), and Hg(II) before being applied to the removal of hazardous and strategic metals from tailing leachates. The sorbent was characterized using Fourier transform infrared spectroscopy and scanning electron microscopy, before and after metal sorption. The acid–base properties of functionalized sorbent were also determined (pHPZC). Uptake kinetics were studied in mono- and multi-component solutions using different equations for kinetic modeling at optimized pH (i.e., pH0: 5.5). Langmuir and Sips equations were applied to model sorption isotherms in single-component solutions. In addition, sorption isotherms in multi-component solutions were used to evaluate the preference for selected metals. Maximum sorption capacities were 0.35 mmol Hg g−1, 0.47 mmol Zn g−1, and 0.50 mmol Ni g−1. Acidified urea solution (pH 2.7) successfully desorbs metal ions from G@MChs (desorption > 90%). The sorbent was tested for the recovery of hazardous and strategic metal ions from acidic leachates of tailings. This study demonstrates the promising performance of G@MChs for the treatment of complex metal-bearing solutions.

The article investigates the sorption method of concentrating rare metals on various sorbents (brands “Purolight”: A-100, A-170, A-172 and BO-020) and determines the optimal conditions for their extraction. It is shown that the extraction of molybdenum on the sorbent “Purolight A-100” was 98%. The proposed sorption mechanism consists in the formation of molybdenum complexes with functional phosphor basics and sulfate groups of sorbents. Sorption of rhenium on the Purolite A-170 sorbent was 93%. Sorption of rhenium on the sorbent BO-020 is described by the Langmuir equation with a maximum static exchange capacity of 94%. Based on the sorption and desorption kinetics of molybdenum and rhenium on various ion-exchange sorbents, it was shown that the sorption of molybdenum and rhenium proceeds most efficiently on low-basic anion exchangers A-100 Mo and A-170, respectively, and after double recleaning of the “rough” rhenium concentrate, ammonium rhenium of qualification was obtained AR-0.

“…Liquid-liquid extraction is a vital separation process in many different fields like in some chemical industries were benzene is removed or recovered [1] from a liquid mixture, or in the area of health where the DNA is extracted [2] to treat different diseases or other health issues. This unit operation is used as well in the food industry, in infant foods [3], in the environment care like reducing copper pollution in water [4], or extraction of a variety of organic pollutants from water using Dispersive liquid-liquid microextraction with the solidification of floating organic drop [5]. Another use is the extraction of metal ions like Co(II), Cd(II), Cu(II), Fe(III), and Ni(II) [6] among others [7].…”

Liquid-liquid extraction is a necessary unit operation used in the recovery of essential solutes like the extraction of DNA in the area of health, the recovery of benzene in industrial processes, and the reduction of contaminants from the water like pesticides in the environment care. With the goal to make studies that give a high contribution in any of the mentioned areas, it is necessary to analyze the trend of research in liquid-liquid extraction. To help researchers to accomplish that aim, it was completed a research development of liquid-liquid extraction from 2007 to 2017 using specialized software. This study assessed a total of 5477 publications related to liquid-liquid extraction which were used to evaluate the trends of publications outputs, primary language, countries, author, institutions, main journal, and keywords. The Republic of China, Spain, and the USA, were the top 3 most productive countries with 1664, 582, and 466 publications respectively. The most productive institution was the Chinese Academy of Sciences followed by Jilin University and Bhabha Atomic Research Centre. The journals with the highest paper production were Chromatography A (11.0%) followed by Talanta (4.3%), and Journal of Separation Science (4.0%). The most keywords used were extraction, and liquid, followed by chromatography. The most productive authors were Hanqi Zhang from Jilin University with 59 publications, followed by Ji Chen from the Chinese Academy of Sciences with 43 papers. 3516 Luis Obregon Quiñones et al.
