Graphene Oxide-terpyridine Conjugate: A Highly Selective Colorimetric and Sensitive Fluorescence Nano-chemosensor for Fe2+ in Aqueous Media
A graphene oxide-terpyridine conjugate (GOTC) based colorimetric and fluorescent nano-chemosensor was synthesized. It showed high selectivity and sensitivity for Fe2+ and Fe3+ ions in neutral aqueous solution over other metal ions such as Li+, Na+, Ba2+, Ca2+, Al3+, Cd2+, Co2+, Cu2+, Hg2+, Mn...
متن کاملA simple but highly sensitive and selective colorimetric and fluorescent probe for Cu2+ in aqueous media.
In this paper, CN-DPA was prepared as an effective colorimetric and fluorescent probe for copper ions (Cu(2+)) in aqueous solution. It exhibits good sensitivity and selectivity for Cu(2+) over other metal ions both in aqueous solution and on a simple colorimetric paper-made test kit. Upon addition of Cu(2+), a remarkable color change from purple to colorless was easily observed by the naked eye...
متن کاملA highly efficient dinuclear Cu(II) chemosensor for colorimetric and fluorescent detection of cyanide in water.
A novel dinuclear copper chemosensor selectively binds cyanide over a wide range of inorganic anions, enabling it to detect cyanide in water up to 0.02 ppm which is 10 times lower than the EPA standard for drinking water.
متن کاملStudies leading to the development of a highly selective colorimetric and fluorescent chemosensor for lysine.
A unique colorimetric change of 1, a pyrene based sensor, from light yellow to pink takes place only in the presence of lysine not other tested naturally occurring α-amino acids.
