4-Tert-octylphenol (4-t-OP), a kind of endocrine-disrupting compounds, is widely distributed in natural water surroundings but can hardly be biodegraded. The advanced oxidation processes (AOPs) have been proved to be an efficient method to degrade 4-t-OP. In this study, the photodegradation of 4-t-OP in aqueous solution promoted by Fe(III) and the(More)
A spiral photoreactor system (SPS) was developed for the degradation of 4-tert-octylphenol (4-t-OP) in aqueous phase. 4-t-OP was previously considered as a endocrine disrupting compound frequently present in water. The direct photodegradation reaction caused by the SPS was found to accord with the characteristic of apparent first-order reaction with(More)
Steady-state and transient-state photolysis experiments were conducted to investigate the degradation of organic ultraviolet filter diethylamino hydroxybenzoyl hexyl benzoate (DHHB) in the aqueous solution by UV/H2O2. Results showed that the obvious degradation of DHHB was not observed under UV irradiation (λ = 254 nm), and the DHHB degradation was(More)
Br(-) and nitrogen-containing organic pollutants, such as amino acids, protein, etc., were often detected in water and wastewater treatment plants using advanced oxidation technologies. All these technologies have one common characteristic, that is, the removal processes involve ·OH. Therefore, it is necessary to study the different reaction pathways among(More)
Knockout is an important method for gene function study, while vector is the core of gene knockout. In order to obtain an effective vector for rapid construction of mutant and essentiality identification of the corresponding gene, we constructed a recombinant plasmid named plDM-T based on the temperature-sensitive and replication- defective plasmid plDM1 by(More)
