Polyacrylonitrile-encapsulated amorphous zirconium phosphate composite adsorbent for Co, Nd and Dy separations
(Elsevier, 2018)
Recycled Nd and Dy from the end-of-life NdFeB permanent magnet is an important supplement for the increasing demand of rare-earth elements. Thus, there is an urgent need to develop an environmentally friendly recycling ...
Ion exchange purification of a silver nitrate electrolyte
(Elsevier, 2018-12-14)
A novel ion exchange process was studied to remove high concentration of Cu impurity from AgNO3 electrolyte was studied. A suitable ion exchange resin was screened using laboratory scale experiments with a synthetic nitrate ...
Novel chromatographic process for the recovery and purification of hydroxy acids from alkaline spent pulping liquors
(Elsevier, 2018-12-14)
In this study, an efficient sequential chromatographic process for recovering hydroxy acids (HAs) from soda and kraft black liquors (BLs) has been developed. Lignin and pulping chemicals are also recovered and can be ...
Recovery of metal oxoanions from basic solutions using cooperative sorption – Separation of Na2MoO4 and NaOH
(Elsevier, 2018-06-01)
Chromatographic separation of molybdate oxoanions and NaOH was studied using cooperative sorption as a method to recover both Mo and the base as concentrated solutions. Commercial non-ionic microporous adsorbents composed ...
Modeling the liquid-liquid extraction equilibrium of iron (III) with hydroxyoxime extractant and equilibrium-based simulation of counter-current copper extraction circuits
(Elsevier, 2018)
The phase equilibrium in the loading and stripping stages of the liquid–liquid extraction of iron (III) with hydroxyoxime extractant in kerosene was studied over a wide range of hydroxyoxime extractant (Acorga M5640, 3–25 ...
