in this study adsorption of 1-chloro-4-nitrobenzene on single walled carbon nanotubes has been investigated.  the effect of contact time, ph, initial concentration of 1-chloro-4-nitrobenzene, adsorbent dosage and temperature on its adsorption has been carried out in order to find optimum adsorption conditions. adsorption isotherms and related constants were also determined. results showed that ...

Overexpression of mutant p53 in cancer cell inactivates the pathways to execute apoptosis and cycle arrest. This study aimed synthesize new kardiena derivative compound, 3-carbethoxy-4(3’-chloro-4’-hydroxy)phenyl-but-3-en-2-one, reactivate Characterization synthetic compound employing melting point, IR, EI-MS, 1H-NMR, 13C-NMR spectra revealed 3-carbethoxy-4(3’-chloro-4’-hydroxy)phenyl-but-3-en-...

this research evaluates the efficiency of nanosized zno in the catalytic ozonation of 4-chloro-2-nitrophenol and determines the effect of ph on heterogeneous catalytic ozonation. the combined use of ozone and zno catalyst leads to conversion of 98% 4-chloro-2-nitrophenol during 5 min. in addition, it was found that in zno catalytic ozonation, the degradation efficiency of 4-chloro-2-nitrophenol...
