Abstract
pH plays many essential functions in living organism while silver find applications in day to day life. However abnormal pH and improper dumping of silver ions can be lethal for living being. Herein, an orange emissive ploymer nanoparticles (OPNP) is synthesized by oxidative method at room temperature using 1, 2 diaminobenzene and potassium peroxodisulfate.The as obtained OPNP is characterized by TEM, FESEM, PXRD, FT-IR, EDX, UV–visible and fluorescence spectroscopy. The fluorescence of the obtained OPNP is highly sensitive to solvents, pH and Ag+ ions. The fluorescent color of the OPNP is tuned from orange to bluish green (560–485 nm) by adjusting the polarity of the solvents. The fluorescence intensity of OPNP increases as the pH is increased from acidic (pH-2) to basic medium (pH-12). The fluorescence of the OPNP is quenched by Ag+ ions, hence it is employed for selective detection of Ag+ ions both in solid and aqueous phase. The calibration plot for Ag+ is linear in the 0–30 μM concentration ranges and its limit of detection is 0.398 μM, which is lower than the permitted limit of WHO. Furthermore, the fluorescent OPNP is explore for determination of Ag+ ion in environmental samples with good recoveries ranging from 95.83 to 103 %.
期刊介绍:
JPPA publishes the results of fundamental studies on all aspects of chemical phenomena induced by interactions between light and molecules/matter of all kinds.
All systems capable of being described at the molecular or integrated multimolecular level are appropriate for the journal. This includes all molecular chemical species as well as biomolecular, supramolecular, polymer and other macromolecular systems, as well as solid state photochemistry. In addition, the journal publishes studies of semiconductor and other photoactive organic and inorganic materials, photocatalysis (organic, inorganic, supramolecular and superconductor).
The scope includes condensed and gas phase photochemistry, as well as synchrotron radiation chemistry. A broad range of processes and techniques in photochemistry are covered such as light induced energy, electron and proton transfer; nonlinear photochemical behavior; mechanistic investigation of photochemical reactions and identification of the products of photochemical reactions; quantum yield determinations and measurements of rate constants for primary and secondary photochemical processes; steady-state and time-resolved emission, ultrafast spectroscopic methods, single molecule spectroscopy, time resolved X-ray diffraction, luminescence microscopy, and scattering spectroscopy applied to photochemistry. Papers in emerging and applied areas such as luminescent sensors, electroluminescence, solar energy conversion, atmospheric photochemistry, environmental remediation, and related photocatalytic chemistry are also welcome.
