Comparison of some newly synthesized chemically modified Amberlite XAD-4 resins for the preconcentration and determination of trace elements by flow injection inductively coupled plasma-mass spectrometry (ICP-MS)
Kara, Derya; Fisher, Andrew; Hill, Steve J. (Royal Soc Chemistry, 2006)XAD copolymer resins may be functionalized with heavy metal ion-selective ligands either by covalent linkage to the polymer backbone or by impregnation. These resins may be tailored to be specific for certain heavy metals ... -
Determination of gallium at trace levels using a spectrofluorimetric method in synthetic u-ga and ga-as solutions
Kara, Derya; Fisher, Andrew; Foulkes, Mike; Hill, Steve J. (Pergamon-Elsevier Science Ltd, 2010)A simple, easy to use and selective spectrofluorimetric method for the determination of trace levels of gallium has been developed. A new Schiff base, N-o-vanillidine-2-amino-p-cresol (OVAC) was synthesized and its ... -
Determination of trace heavy metals in soil and sediments by atomic spectrometry following preconcentration with schiff bases on amberlite xad-4
Kara, Derya; Fisher, Andrew; Hill, Steve J. (Elsevier Science Bv, 2009)A matrix separation and analyte preconcentration system using Amberlite XAD copolymer resins functionalized by Schiff base reactions coupled with atomic spectrometry has been developed. Three different functionalized ... -
Flow injection determination of aluminium by spectrofluorimetric detection after complexation with N-o-vanillidine-2-amino-p-cresol: The application to natural waters
Kara, Derya; Fisher, Andrew; Hill, Steve J. (Elsevier Science Bv, 2008)An on-line flow injection spectrofluorimetric method for the direct determination of aluminium in water samples is described. The method is based on the reaction of aluminium with N-o-vanillidine-2-amino-p-cresol (OVAC) ... -
A novel ligandless-dispersive liquid-liquid microextraction method for matrix elimination and the preconcentration of rare earth elements from natural waters
Çelik, İbrahim; Kara, Derya; Karadaş, Cennet; Fisher, Andrew; Hill, Steve J. (Elsevier Science BV, 2015)A new, simple, efficient and rapid separation method based on ligandless-dispersive liquid-liquid microextraction (LL-DLLME) was developed for the preconcentration of rare earth elements (REEs) (La, Ce, Pr, Nd, Sm, Eu, Gd, ... -
