(2011)The adsorption of hydrophobically modified polyelectrolytes derived from poly(maleic anhydride-alt-styrene) (P(MA-alt-St)) containing in their side chain aryl-alkyl groups onto amino- or methyl-terminated silicon wafers ...
-
(Elsevier B.V., 2016)Adsorption of As (V) by poly (N-octyl-4-vinylpyridinium) bromide (P4VPyC8), used as solid phase, was studied. Determination of As (V) was carried out by direct measurement of the fluorescence intensity on the solid phase. ...
-
(2013)ABSTRACT Chloride selective polymeric liquid membrane electrode has been developed by using Bis-(2-ethylhexyl) Sebacate (DOS) as plasticizer and 2-[5-(4-nitrophenyl) furyl]-4,5-diphenyl imidazole (FFDFIN) as ionophore. ...
-
(American Scientific Publishers, 2013)With the purpose of obtaining stable and non-toxic nanocomposites with potential biomedical applications we coated gold nanoparticles (AuNP) with chitosan (CHI) and CHI grafted with poly(Nisopropilacrylamide) (PNIPAAm) and ...
-
(Universidad de ChileCyberDocs, 2010)Los complejos Cu2(u-O2CR)4L2 fueron sintetizados a partir de Cu2(OH)2CO3 y el correspondiente RCOOH; donde R: C10H13- y PhCH=CH2-, además L: N,N-dimetilformamida , dimetilsulfóxido o tetrahidrofurano. Estos fueron ...
-
(2011)Quinoa protein/chitosan films were obtained by solution casting of blends of quinoa protein extract (PE) and chitosan (CH). Films from a PE/CH blend were characterized by FTIR, X-ray diffraction, thermal analysis, and SEM. ...
-
(2013)The construction and evaluation of an all-solid-state type electrode selective to nitrate based on poly(vinyl chloride) (PVC) as polymeric membrane, diethyl phthalate as plasticizer and tetradecilammonium nitrate (TDAN) ...
-
(1992)Relative reactivities of potassium persulfate (KPS) and ferrous ammonium sulfate-potassium persulfate (FAS-KPS) systems, in aqueous medium, as initiators for grafting of methyl methacrylate (MMA) onto chitin, were studied. ...
-
(Universidad de Chile, 2023)Los compósitos laminares reforzados con fibra de carbono (CLRFC) son materiales atractivos en numerosas aplicaciones relacionadas con áreas como deportes, aeroespacial, automotriz, energía eólica, y defensa, entre otras, ...
-
(Elsevier, 2019)Quinoa proteins (QP) have promise as a potential source of novel food ingredients, and it is of great interest to know how high-intensity ultrasound (HIUS) treatments affect the properties of QP. This work aimed to study ...
-
(2004)A potentiometric all-solid-state type ion-selective electrode (ISE) for NO3 - was constructed and characterized. It is based on a mixture of tetra-decyl-ammonium nitrate (TDAN) as ionophore, di-butyl phthalate (DBP) as ...
-
(Sociedad Chilena de Quimica, 2010)l-furoyl-3,3-diethylthiourea was used as a novel neutral carrier in ion selective electrode for copperII detection and determination. The Cu2+ selective plasticized polyvinyl chloride (PVC) membrane electrode exhibited ...
-
