The hypercrosslinked polystyrene adsorbents of LY-4 and LY-5 were prepared By Friedel-Crafts post-crosslinking reaction with phenol and naphtho. The physical properties of absorbents showed that both phenolic hydroxyl group content and BET surface area of LM-5 are higher than LM-4. Accordingto the adsorption experiment in aqueous solution, the adsorption capacity of aniline onto LM-5 is bigger than...
The effect of inorganic ions on Fenton's reagent to degrade phenol in water is studied. Experimental results show that ferric ions can enhance the catalyst-oxidation ability of Fenton's reagent. Phosphate,chloride ions, copper ions and carbonate ions will suppress the catalyst-oxidation ability, and the inhibition ability of ions is: H2PO4->;Cl- >;Cu2+>;HCO3-~CO32-.For the ions of sulfate...
Isotherms and kinetics of adsorption of phenol on microwave organic modified montmorillonite were investigated. The results show that the adsorption capacity of M-OMt was determined as 58.14 mg/g at the conditions of pH7.2 contact time of 1 hour and temperature of 20 C. The adsorption data is a good fit with Freundlich isotherm, and the adsorption kinetics is in better agreement with pseudo-second...
The degradation and its kinetics of chlorine chlorination of phenol in disinfection process was studied. The influencing factors were investigated, such as chlorine dosage, temperature and background organic compound and so on. The experimental results showed that the degradation of phenol by chlorine followed second-order kinetics. The temperature influenced the reaction sharply, and it followed...
