iron(III)metal ion extractionionic liquidpolymer inclusion membraneCTA matrixIn this study, liquid membranes denoted as polymer inclusion membranes (PIMs) consisting of cellulose triacetate (CTA) as a polymer matrix, o-nitrophenyl octyl ether (NPOE) as a plasticiser and phosphonium ionic liquids, ...
It is predicted that the continuously increasing demand for the energy-critical element of lithium will soon exceed its availability, rendering it a geopolitically significant resource. The present work critically reviews recent reports on Li+ selective

Open circuit potential measurements and cyclic voltammetry of chromium in deaerated aqueous H2SO4 solution of pH 1 without and containing NaCl in the concentration range 0.5 – 4 M revealed that chromium exhibits two stable open circuit potentials having the character of a Wagner–Traud corrosion pot...
ions present in the solution. After the electrons left FEP*, the latter returns to its ground state (FEP), and the catalytic cycle continues if ultrasonic conditions are maintained. A more detailed explanation of the mechanism of contact-electrification and CEC is presented in Supplementary Note1...
The electrochemical behavior of iron in aqueous phosphate solutions (0.005–0.1M) of pH∼8 at room temperature was investigated with an emphasis on the effect of chloride and /or sulfate ions on the initiation of the localized attack. Electrochemical techniques were complemented by SEM microscopy,...
Phosphoric acid-induced activation of sepiolite for enhanced As(III) adsorption: role of in situ deposition of nano-hydroxyapatite AQUEOUS-SOLUTIONARSENIC IIIZEROVALENT IRONA simple and effective approach was introduced to modify natural calcium-rich sepiolite (SEP) by in situ deposition ...

In the second step, i.e. when R∗<R<2, the precipitation of the excess of FeIIaq present in solution leads to the formation of Fe(OH)2. The (x,R∗) of points E* presented in the mass-balance diagram in Fig. 4 increases roughly linearly according to R∗=αx where α=7±...
In water systems, corrosion of piping and fittings in water delivery systems can release metals (e.g. iron, copper and zinc) in water and also metal-containing sediments occasionally released from pipe surfaces can elevate the concentrations of these metals. Aluminum is generally present at low ...
Magnetic adsorbents are a specific material matrix that hosts iron particles (usually magnetic nanoparticles, such as Fe3O4)26. The base material could be carbon, CS, polymers, starch, or biomass. As illustrated in Fig.2, the adsorption process is affected by the magnetic field, surface charge...
