Fluted pumpkin stem waste, which is both a waste and pollutant, was chemically modified with ortho-phosphoric acid and used to adsorb phenol and chlorophenol in fixed bed micro column It was found that the carbon bed sorption capacity for phenol and chlorophenol (77.20 and 80.0 mg/g) were higher than the equilibrium sorption studies. The critical bed depth increased with increasing phenol and c...

3,4-Dichlorophenol (1) crystallizes in the tetragonal space group I41/a with a short axis of 3.7926 (9) Å. The structure is unique in that both type I and type II Cl⋯Cl interactions are present, these contact types being distinguished by the angle ranges of the respective C-Cl⋯Cl angles. The present study shows that these two types of contacts are utterly different. The crystal structures of 4-...

Hydrogen and halogen bonds are important anisotropic attractive interactions in the molecular crystalline state. 2,6-dibromophenol (1) was analyzed by single-crystal X-ray diffraction for first time. The intermolecular interaction pattern studied Hirshfeld surface analysis along with 2D fingerprint diagrams. characteristic that dominate crystal packing electrostatic type-II Br⋅⋅⋅Br interactions...

In order to assess the applicability of using microelectrodes as a tool for inhibition tests, temporal and spatial inhibitory effects of 2-chlorophenol (2-CP) on O(2) respiration and nitrification activities in municipal wastewater biofilms were investigated using microelectrodes for O(2) and NH(4)(+). The time-course microelectrode measurements demonstrated that 2-CP inhibited O(2) respiration...

background: chlorophenols are classified as priority toxic pollutants. these acidic organic compounds present a serious potential hazard for human health and aquatic life. chlorophenols accumulate in water, soil and air due to high stability, and impart an unpleasant taste and odor to drinking water and can exert negative effects on different biological processes. among the different methods of...

Concentrations of 3-chlorophenol and 4-chlorophenol below their minimal inhibitory concentrations were found to increase the permeability of Pseudomonas aeruginosa cells to protons. Levels of such activity were assessed in suspensions of cells prepared from chemostat-grown cultures, limited by either magnesium (Mg-lim) or glucose (G-lim), with the use of five growth rates. Drug concentrations r...

Biological co-metabolism is an economical and efficient technique for treating refractory organic matter, in recent years, it has been widely used the treatment of chlorophenol-containing wastewater. It found that many conditions affect bio efficiency, such as carbon source type, content, microorganism types, environmental factors. The concentration experiment showed when dosage ratio sodium ac...
