Bioelectrochemical system for recalcitrant p-nitrophenol removal.
Bioelectrochemical system (BES) for recalcitrant p-nitrophenol (PNP) removal was investigated in this study. Effective removal of PNP at rates up to 9.14 ± 0.48 mol m(-3)d(-1) was achieved at an energy consumption as low as 0.010 ± 0.002 kWh mol(-1) PNP. PNP removal rate was enhanced with negative cathode potential, increased influent PNP concentration and shortened hydraulic retention time (HR...
متن کاملTheoretical and experimental electrostatic potential around the m-nitrophenol molecule.
This work concerns a comparison of experimental and theoretical results of the electron charge density distribution and the electrostatic potential around the m-nitrophenol molecule (m-NPH) known for its interesting physical characteristics. The molecular experimental results have been obtained from a high-resolution X-ray diffraction study. Theoretical investigations were performed using the D...
متن کاملDraft: Evidence on the carcinogenicity of 4-amino-2-nitrophenol
PREFACE The Safe Drinking Water and Toxic Enforcement Act of 1986 (Proposition 65, California Health and Safety Code 25249.5 et seq.) requires that the Governor cause to be published a list of those chemicals " known to the state " to cause cancer or reproductive toxicity. The Act specifies that " a chemical is known to the state to cause cancer or reproductive toxicity...if in the opinion of t...
متن کاملKinetics of biodegradation of p-nitrophenol by different bacteria.
Three bacterial species, i.e., Ralstonia sp. SJ98, Arthrobacter protophormiae RKJ100, and Burkholderia cepacia RKJ200, have been examined for their efficiency and kinetics behavior toward PNP degradation. All the three bacteria utilized PNP as the sole source of carbon, nitrogen, and energy. The rates of radiolabeled [U-(14)C]PNP degradation by all the bacteria were higher in the nitrogen-free ...
متن کاملBioremediation of p-Nitrophenol by Pseudomonas putida 1274 strain
BACKGROUND p-Nitrophenol (PNP) occurs as contaminants of industrial effluents and it is the most important environmental pollutant and causes significant health and environmental risks, because it is toxic to many living organisms. Nevertheless, the information regarding PNP degradation pathways and their enzymes remain limited. OBJECTIVE To evaluate the efficacy of the Pseudomonas Putida 127...
