In this study, two new salicylideneaniline derivative compounds which are an isomer of each other have been synthesized and characterized by X-Ray Diffraction (XRD) technique, IR spectroscopy, and theoretical method. While (E)-4-(dihydroxyamino)-2-(((4-fluorophenyl)imino) methyl)phenol (1), crystalizes triclinic P-1 space group, (E)-4-(dihydroxyamino)-2-(((3-fluorophenyl)im...
Alkaline water was used for the microwave-assisted extraction of some priority pollutants of phenols in sediments, i.e. phenol (Ph), 2-chlorophenol (2CP), 2,4-dichlorophenol (2,4DCP), 4-chlorophenol (4CP), 4-dinitrophenol (4NP) and pentachlorophenol (PCP). This organic solvent-free extraction procedure was optimized by studying the parameters such as pH, volume of the alkaline water, extraction...
Nano-ZnO was employed for the adsorption of 4C2NP from aqueous solutions in batch equilibriumexperiments to investigate its adsorption properties. The quantity of 4C2NP adsorbed onto nano- ZnOsurface was measured by UV-Vis spectrophotometer. The effects of contact time, adsorbent dose, pH, andinitial concentration of 4C2NP were investigated. The adsorption found to be strongly influenced by all...
A sensitive screen-printed electrode modified with multi-walled carbon nanotubes (MWCNTs/SPE) was applied to determine simultaneously m-nitrophenol, o-nitrophenol and p-nitrophenol. The electrochemical response showed that o-nitrophenol, m-nitrophenol and p-nitrophenol were entirely separated at the MWCNTs/SPE interface. Under the optimized conditions, it was found that the detection limits wer...
A functional Cu(I) boron imidazolate framework (BIF) with a ladder-chain structure can not only change to another single-chain structure by incorporating 4,4'-bipyridine, but can also act as a reducing agent to load trimetal Au-Ag-Pd nanoparticles directly; the BIF with loaded noble NPs showed an excellent reduction effect on 4-nitrophenol. Moreover, we obtained a porous borocarbonitride by the...
