Zn(II) AND Cu(II) UPTAKE FROM ACID SOLUTIONS WITH MICROCAPSULES CONTAINING A NON-SPECIFIC ALKYL PHOSPHONIC EXTRACTANT
(Sociedad Chilena de Química, 2005)
High-throughput platform for synthesis of melamine-formaldehyde microcapsules
(American Chemical Society, 2017-06-02)
The synthesis of microcapsules via in situ polymerization is a labor-intensive and time-consuming process, where many composition and process factors affect the microcapsule formation and its morphology. Herein, we report ...
Uptake of copper (II) ions from acidic aqueous solutions using a continuous column packed with microcapsules containing a β-hydroxyoximic compound
In this paper, the uptake of Cu(II) ions from an acidic aqueous solution using a continuous column packed with microcapsules containing the chelating extractant LIX-860 N-IC was examined. A simple, economical method was ...
Immobilization of rhodamine 6G in calcium alginate microcapsules based on aromatic-aromatic interactions with poly(sodium 4-styrenesulfonate)
Immobilization of rhodamine 6G in calcium alginate microcapsules was achieved using the polyanion bearing negatively charged aromatic groups poly(sodium 4-styrenesulfonate) as complexing agent. The immobilization of the ...
Effect of the preparation method on the structure of linseed oil-filled poly(urea-formaldehyde) microcapsules
(Elsevier Science Sa, 2016-04-29)
tLinseed oil was satisfactorily encapsulated in urea-formaldehyde (UF) shell by one acid stage polymer-ization. This was confirmed by thermal analyses (TGA) and FTIR studies. Microcapsules produced by oneacid stage were ...
Microencapsulation of trioctylamine in polymeric matrices for removing Zn(II) and Cu(II) from chloride aqueous solutions
(Sociedad Chilena de Química, 2010)
The microencapsulation of the non-specific basic extractant trioctylamine in polymeric matrices synthesized from styrene and divinylbenzene was studied. The microcapsules were prepared by adding the amine compound during ...
Zn(II) and Cu(II) Uptake from Acid Solutions with Microcapsules Containing a Non-Specific Alkyl Phosphonic Extractant
(SOCIEDAD CHILENA DE QUIMICA, 2005-12)
It is studied the uptake of Zn(II) and Cu(II) from acid aqueous solutions using microcapsules containing 2-ethylhexylphosphonic acid mono-2-ethylhexyl ester, a non-specific extractant, as an alternative method for metals ...
