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 ...
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 ...
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 ...
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 ...
Melamine -formaldehyde microcapsules: micro - and nanostructural characterization with electron microscopy
(Cambridge University Press, 2016-11)
A systematic study has been carried out to compare the surface morphology, shell thickness, mechanical properties and binding behavior of melamine formaldehyde icrocapsules of 5 to 30 µm diameter size with various amounts ...
Investigation on extraction rate of lanthanides with extractant-impregnated microcapsule
Extraction of lanthanum, samarium and erbium into a microcapsule containing 2-ethylhexylphosphonic acid mono-2-ethylhexyl ester (EHPNA) is studied. The extraction kinetic model used to predict uptake curves is based on the ...
MICROENCAPSULATION OF TRIOCTYLAMINE IN POLYMERIC MATRICES FOR REMOVING Zn(II) AND Cu(II) FROM CHLORIDE AQUEOUS SOLUTIONS
