phenol and phenolic compounds are among the most recognized environmental pollutants which exist in industrial wastewater and enter the biological cycles due to the solubility in water. Bioremediation is one of the cost-effective and Eco-friendly methods for phenol removal. In this study, the most effective phenol-degrading bacterial strain was isolated and identified from the shores of the Oma...

Phenol is a ubiquitous organic contaminant in drinking water. Biodegradation plays an important role in the elimination of phenol pollution in the environment, but the information about phenol removal by drinking water biofilters is still lacking. Herein, we study an acclimated bacterial community that can degrade over 80% of 300 mg/L phenol within 3 days. PCR detection of genotypes involved in...

a binuclear macrocyclic ligand containing dissimilar n(amine)2o2 and n(imine)2o2 coordination sites sharing two phenolic oxygen atoms, was prepared by cyclic condensation of dialdehyde precursor l1h2 with 1,3-diaminopropane. the ligand includes two propionitrile pendant arms on the amine nitrogen atoms. the homobimetallic complex [znl2zn(oac)]pf6 was synthesized by one step procedure. heterobim...

Phenol formaldehyde (PF) resins are widely used as wood adhesives in the industrial production of exterior-grade plywood panels, oriented strand board panels and particleboards due to their superior performance including high bonding strength, heat resistance, excellent water resistance and chemical stability1. However, phenol, one raw material for the synthesis of PF resins, is a petroleum-bas...

background and objectives: dairy companies always try to increase the quantity and quality of milk production. according to the positive impact of different plants on milk production of cattle, this study was carried out to standardize a galactogogue herbal mixture based on its total phenol and flavonol contents and antioxidant activity.  methods: a mixture of galega officinalis l. and nigella ...

The present study analyses the potential of acid treated chitosan for simultaneous co-adsorptive removal of phenol and cyanide from a binary waste water solution. The effects of parameters like pH, temperature, initial concentration, adsorbent dose, and adsorbent size were studied. At an optimum pH of 8, temperature of 300C, initial phenol and cyanide concentration of 200 mg/L and 20 mg/L respe...

Phenol biodegradation using acclimated activated sludge was investigated in batch and fedbatch cultures with variable initial concentrations of phenol and biomass. The batch experimental data show a cell growth after phenol exhaustion, making the use of a conventional Haldane model, for which specific growth rate μ = 0 when substrate S = 0, inadequate to describe biomass growth profiles. On the...

A novel route to facilitate the degradation of phenol is reported. This new approach is based on a micellar polyoxometalate (POM) catalytic system. The micellar POM catalyst could promote phenol molecules' degradation into a simple inorganic compound such as CO2 using only air as an oxidant under room conditions. The results of the recycling experiment suggests that the micellar POMs may be use...

Simultaneous determination of multicomponents of phenol, resorcinol and catechol with a chemometric technique a PCranking artificial neural network (PCranking-ANN) algorithm is reported in this study. Based on the data correlation coefficient method, 3 representative PCs are selected from the scores of original UV spectral data (35 PCs) as the original input patterns for ANN to build a neural n...

Treating a synthetic wastewater containing phenol as the sole substrate at 26°C, an upflow anaerobic sludge blanket reactor was able to remove over 98% of phenol up to 1,260 mg/l in wastewater with 12 h of hydraulic retention time, corresponding to 6.0 g-COD/(l·day). Results showed that benzoate was the key intermediate of phenol degradation. Conversion of benzoate to methane was suppressed by ...
