Degradation of phenolics by members of soil microflora is an important means by which these substances are removed from the environment thus reducing environmental pollution. Biodegradation by microorganisms offers unique opportunities to destroy or render phenolic compounds. A bacterium, PU1, identified as Pseudomonas fluorescens PU1, was investigated for its ability to grow on and degrade phe...

It has become the new focus in the field of water treatment to deal with the difficult degradable organic pollutants using the transition metal and the transition metal ion. This paper examined a new activator of Fe in persulfate (K2S2O8) activation based on strong oxidizer of sulfate radicals (SO·-) for catalytic oxidation of phenol. Discuss the reaction time, activator dosing amount, K2S2O8 d...

A new method was established for the simultaneous determination of the migration amounts of bisphenol A (BPA) and phenol from polycarbonate (PC) bottles based on subcritical water extraction (SWE) and high performance liquid chromatography. The optimum extraction conditions included an extraction temperature of 120 degree C, a pressure of 6.89 MPa (1000 psi), a static extraction time of 1 h and...

Phenol has various medical applications but can cause convulsions and cardiac arrhythmia suggestive of K+ channel block. We examined phenol inhibition of the delayed-rectifier RCK1 (Kv1.1) K+ channel cloned from rat brain and expressed in Xenopus laevis oocytes. Phenol (2.5 mM) caused a 43 +/- 5 mV depolarizing shift in the RCK1 half-activation voltage (Vg) but only a 10 +/- 3% decrease in the ...

A new clinic was set up to deal with all toenail problems referred to a large general hospital. Ingrowing toenails were the commonest problem dealt with and phenol cauterization, either partial or complete, was the standard form of treatment. Over a 2-year period 1013 phenol cauterizations were carried out on 631 patients. After a minimum of 12 months follow-up, the recurrence rate was 2.96%. A...

The percentage removal of phenol from aqueous solution by emulsion liquid membrane and emulsion leakage was investigated experimentally for various parameters such as membrane:internal phase ratio, membrane:external phase ratio, emulsification speed, emulsification time, carrier concentration, surfactant concentration and internal agent concentration. These parameters strongly influence the per...

Phenol was analyzed by both gas chromatography–flame ionization detection (GC–FID) and gas chromatography–mass spectrometry (GC–MS) to compare the techniques and to find out if GCFID is a suitable tool for the analysis of phenol extracted from environmentally important phenol in water. After the treatment of water with CuSO4 and H3PO4, phenol in the water was extracted with dichloromethane. The...

HART, LARRY G., ANTHONY M. GUARINO, AND RICHARD H, ADAMSON. Effects of phenobarbital on biliary excretion of organic acids 2*lz male and female rats. Am. J. Physiol. 2 17( 1) : 46-52. 1969.-The effects of phenobarbital pretreatment on the biliary excretion of four organic anions, indocyanine green (ICG), chlorothiazide (CTZ), phenol red, and probenecid, were investigated. Indocyanine green and ...

An airlift inner-loop bioreactor packed with honeycomb-like ceramic as the carrier was developed and its capacity to immobilize microorganism was studied through adding bacteria, Achromobacter sp., capable of degrading 2,4-dichlorophenol (2,4-DCP), directly to the reactor under continuous operation. Effects of phenol in the feed with 2,4-DCP on 2,4-DCP removal were investigated under fed-batch ...

The nervous system from nineteen patients with malignant disease who had intrathecal injections for the relief of pain was examined. In eighteen patients one or more injections of phenol in iophendylate or glycerol had been given; in six of them injections of silver nitrate and phenol in iophendylate or glycerol were also given. In one patient a single injection of silver nitrate and phenol in ...
