Review on cadmium removal from aqueous solutions
TL;DR: In this article, a review of various types of adsorbents which have been used for removing cadmium from aqueous solutions is presented, which includes precipitation, ion exchange, solvent extraction and adsorption.
Journal ArticleDOI
Study on removal of cadmium from wastewater by emulsion liquid membrane.
TL;DR: To determine the optimum operation conditions, the effect of several parameters such as surfactant concentration, carrier concentration, pH of external and internal phases, oil to internal phase volume ratio, emulsion to external phaseVolume ratio, solvent type, solute concentration, presence of iodide and chloride in external phase, and mixing conditions have been investigated.

Facilitated Cd(II) transport across CTA polymer inclusion membrane using anion (Aliquat 336) and cation (D2EHPA) metal carriers
TL;DR: In this paper, the authors compare the efficiency of the recovery process in the case of Cd(II) using extractants such as D2EHPA and Aliquat 336 that can form complexes with the cation Cd2+ or the anions CdCl3− and CdC42−, respectively.

Removal characteristics of metal ions using degreased coffee beans: adsorption equilibrium of cadmium(II).
TL;DR: The feasibility of using coffee beans after being dripped and degreased (DCB) as an adsorbent for base metals such as copper, zinc, lead, iron and cadmium were examined and suggested that DCB behaves as a cation exchanger.
Journal ArticleDOI
Review on solvent extraction of cadmium from various solutions
TL;DR: In this paper, the solvent extraction processes for the extraction and recovery of hazardous metal cadmium from aqueous solutions associated with commonly metallic and non-metallic ions, such as sulfate, chloride, nitrate and phosphate have been reviewed.

EXTRACTION OF Am(lll) AND Eu(lll) NITRATES BY 2-6-DI-(5,6-DIPROPYL-1,2,4-TRIAZIN-3-YL)PYRIDINES 1
TL;DR: In this paper, the authors used n-propyl (DPTP) to form dimers and trimers in mixed branched alkanes modified with 2-ethyl-1-hexanol and showed that the self-association is supported by enhancing the HNO3 concentration from 0·3 to 0·9 M.
