Rafal Sitko,Edyta Turek,Beata Zawisza,Ewa Malicka,Ewa Talik,J. Heimann,Anna Gagor,Barbara Feist,Roman Wrzalik +8 more
TL;DR: Potential application of GO in analytical chemistry as a solid sorbent for preconcentration of trace elements and in heavy metal ion pollution cleanup results from its maximum adsorption capacities that are much higher than those of any of the currently reported sorbents.
Journal ArticleDOI
Green approach for ultratrace determination of divalent metal ions and arsenic species using total-reflection X-ray fluorescence spectrometry and mercapto-modified graphene oxide nanosheets as a novel adsorbent.
TL;DR: GO-SH can be applied to the arsenic speciation due to its selectivity toward arsenite and is suitable for the analysis of water, including high salinity samples difficult to analyze using other spectroscopy techniques.
Journal ArticleDOI
Graphene oxide/cellulose membranes in adsorption of divalent metal ions
TL;DR: In this article, two types of graphene oxide/cellulose membranes were fabricated to perform effective adsorption of heavy metal ions: cobalt, nickel, copper, zinc, cadmium and lead.
Journal ArticleDOI
Suspended aminosilanized graphene oxide nanosheets for selective preconcentration of lead ions and ultrasensitive determination by electrothermal atomic absorption spectrometry.
TL;DR: The GO-NH2 is characterized by high selectivity toward Pb(II) ions and can be successfully used for analysis of various water samples with excellent enrichment factors of 100 and detection limits of 9.4 ng L(-1).
Journal ArticleDOI
Preconcentration of Fe(III), Co(II), Ni(II), Cu(II), Zn(II) and Pb(II) with ethylenediamine-modified graphene oxide
TL;DR: A novel solid phase sorbent synthesized by coupling graphene oxide (GO) to ethylenediamine (EDA) is capable of adsorbing the ions of iron, cobalt, nickel, copper, zinc and lead and was successfully applied to the determination of trace amounts of these metal ions in water samples.
