Determination of benzomercaptans in environmental complex samples by combining zeolitic imidazolate framework-8-based solid-phase extraction and high-performance liquid chromatography with UV detection

Martinez-Perez-Cejuela, Hector; Mompo-Rosello, Oscar; Crespi-Sanchez, Neus; Palomino Cabello, Carlos; Catalá-Icardo, Mónica; Simo-Alfonso, Ernesto F.; Herrero-Martinez, Jose Manuel (Elsevier, 2020-11-08)

[EN] In this work, the synthesis of zeolitic imidazolate framework-8 (ZIF-8) crystals and their subsequent application as effective sorbents for extraction and preconcentration of several benzomercaptans from environmental ...
Estudio de la presencia de plásticos y microplásticos en arenas de playa de la zona costera valenciana y su posible lixiviación de BPA

Rivadeneira Gamez, Dimara Inmaculada (Universitat Politècnica de València, 2024-09-05)

[ES] La gran resistencia de los plásticos y el uso frecuente de materiales plásticos nuevos (como botellas, latas, fibras, etc.) que no se reciclan, provoca que estos se acumulen en el medio ambiente, especialmente en ...
Extraction and preconcentration of organophosphorus pesticides in water by using a polymethacrylate-based sorbent modified with magnetic nanoparticles

Meseguer-Lloret, S.; Torres-Cartas, Sagrario; Catalá-Icardo, Mónica; Simó-Alfonso, Ernesto F.; Herrero-Martínez, José Manuel (Springer-Verlag, 2017)

[EN] A polymethacrylate-based sorbent modified with magnetic nanoparticles (MNPs) has been synthesized and used as sorbent for solid-phase extraction (SPE) and magnetic solid-phase extraction (MSPE) of three organophosphorus ...
Fast determination of thiacloprid by photoinduced chemiluminescence

Catalá Icardo, Mónica; López Paz, José Luis; Pérez Plancha, Laura María (Society for Applied Spectroscopy, 2014-06)

A new and sensitive application of the chemiluminescence detection has been developed for the determination of the pesticide thiacloprid in water. It was based on the on-line photoreaction of thiacloprid in basic medium, ...
FI on-line chemiluminescence reaction for determination of MCPA in water samples

Torres Cartas, Sagrario; Gómez Benito, Carmen; Meseguer-Lloret, Susana (Springer Verlag, 2012)

This paper reports an economic, simple, and rapid FI-CL method for the determination of MCPA. This method requires simple instrumentation and it is fast enough to be used in routine analyses. A chemiluminescence signal is ...
Flow injection photoinduced chemiluminescence determination of imazalil in water samples

Meseguer-Lloret, S.; Torres-Cartas, Sagrario; Gómez Benito, Carmen (Springer Verlag (Germany), 2010-12)

[EN] In this work, a fast, simple and economic method is proposed for the determination of imazalil in water samples by flow injection photoinduced chemiluminescence. In this method, imazalil degrades in basic media through ...
Native vs photoinduced chemiluminescence in dimethoate determination

Catalá Icardo, Mónica; López Paz, José Luis; Choves Barón, Cristina; Pena Badena, A. (ELSEVIER SCIENCE BV, 2012)

The determination of dimethoate using either its native chemiluminescent (CL) properties or its photoinduced chemiluminescence obtained by irradiation with a 15W low-pressure mercury lamp was studied. Thereby, two flow ...
Polymer-based materials modified with magnetite nanoparticles for enrichment of phospholipids

Ten-Domenech. I.; Martínez-Pérez-Cejuela, H.; Simó-Alfonso, E.F.; Torres-Cartas, Sagrario; Meseguer-Lloret, S.; Herrero Martínez, J.M. (Elsevier, 2018)

[EN] A polymeric material modified with magnetic nanoparticles (MNPs) has been synthesized and evaluated as sorbent both for solid-phase extraction (SPE) and dispersive magnetic solid-phase extraction (MSPE) of ...
