The Effect of pH on Nanosized ZnO Catalyzed Degradation of 4-Chloro-2-Nitrophenol via Ozonation
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...

متن کاملADSORPTION OF p-NITROPHENOL IN THREE DIFFERENT ACTIVATED CARBONS AT DIFFERENT pH
Adsorption of p-Nitrophenol by three different activated carbons (F100, S.E.I. and B.D.H.) was carried out at 301 K and at controlled pH conditions. Two different adsorption models (Langmuir model and Freundlich model) were studied and compared. The adsorption capacity of the carbons depends on the Point of Zero Charge (PZC) and surface area of the carbons. Adsorption of the solute at higher pH...
متن کاملRemoval of 4-Nitrophenol and Organic Dyes from Aqueous Solution Using Ag/ZnO Nanocomposite Prepared by Euphorbia peplus L. Extract
Background & objectives: Nitroanene compounds and toxic dyes are considered major pollutants in sewage of various industries. These synthetic organic compounds are highly toxic and one of the most resistant pollutants in the environment. Developing a simple and effective method to destroy non-biodegradable pollutants into non-hazardous products is one of the major challenges in environmental st...
