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...

AIMS Despite its long history, the acid fast smear remains unstandardised. Technical variations in both the preparation of clinical material and subsequent staining mean that smear sensitivity relative to culture may vary from 50% to over 80%. This study assessed the sensitivity of acid fast microscopy at each of five stages of sample preparation and by both commonly used staining methods. ME...

Plant peroxidases have strong potential utility for decontamination of phenol-polluted wastewater. However, large-scale use of these enzymes for phenol depollution requires a source of cheap, abundant, and easily accessible peroxidase-containing material. In this study, we show that potato pulp, a waste product of the starch industry, contains large amounts of active peroxidases. We demonstrate...

Objective: This study was aimed to compare the efficacy of cleaning techniques using hot water treatment soap containing 2% triclosan and chemical antiseptics in reducing bacterial contamination observed on shared musical wind instruments.
 Methods: The trumpet, mellophone, trombone, tuba were evaluated this study. To count initial colonies instrument, total amount bacteria adhered it extr...

background this study demonstrates the removal efficiency of phenol from aqueous solutions by electrocoagulation process using aluminum electrodes and also investigates solution chemistry and polymeric natural organic matters on removal efficiency objectives: the main aim of this work was to focus on the removal of phenol by electrocoagulation process using aluminum electrodes. materials and me...

The regeneration of activated carbons used for the decontamination of water and wastewater polluted with organic compounds related to the pharmaceutical industry, has been studied in this work. To this end, the pyrolysis of exhausted activated carbons was performed in a quartz reactor. The influence of the pyrolysis of saturated activated carbons on their adsorptive capacities and porous struct...

To eliminate the consequences of accidental spill phenol, results neutralization soils contaminated with phenol are presented. As for analysis by geological-lithological section it was found that in areas contamination soil has a surface soil-plant layer thickness about 0.5m, then there is heavy clay up to 7.0 m and finally sand saturated groundwater observed. It revealed according physical mec...
