In this study, a successful degradation of phenol was achieved by a combination of processes, ultrasonic irradiation and periodate. The effect of pH, dosage of IO4-, dosage of initial phenol and ultrasonic irradiation time on the phenol degradation were examined. Furthermore, the impacts of ion intensity on phenol degradation were examined. The findings indicated that the disgrace ratio advance...

A laboratory scale activated sludge sequencing batch reactor was operated in order to obtain total removal of influent ammonia (200; 300 and 500 mg NH3-N.L) with sustained nitrite accumulation at the end of the aerobic stages with phenol (1,000 mg C6H5OH.L) as the carbon source for denitrifying microorganisms during the anoxic stages. Ammonia removal above 95% and ratios of (NO2-N / (NO2-N + NO...

abstract   background: phenol and its compounds are common environmental contaminants, which because of their potential harm to human health, are considered as priority pollutants. in this study, the potential of ostrich feather for phenol removing from aqueous solution was studied. methods: removing the phenol from the aqueous solution was studied via considering the effect of absorbent (0.1, ...

Plant materials have been found useful in decontamination of water polluted with phenolic compounds. The detoxification effect is due to peroxidases contained in plant tissue. Enzyme mediated oxidative coupling of phenol is followed by precipitation of the formed polymer and its removal from the aqueous phase. A synthetic wastewater buffered at pH = 7.4 containing 0.9 mM phenol was treated in t...
