This study reported the feasibility of flushing remediation of Cu contaminated soil using thiacalix arenetetrasulfonate (TCAS) reagent. Batch experiments were performed to test the factors influencing remediation of Cu contaminated soil. The effects of pH value, initial conentration and contact time.on the removal capacities of Cu by TCAS reagent had been studied. The results showed that the TCAS...
Organochlorine pesticides were detected and analyzed in surface water, bottom water and porewater from Honghu Lake, middle of China. The concentrations of total HCHs in surface water and bottom water were 3.52-5.68 ng/L and 3.77-6.86 ng/L respectively, and the concentrations of total DDTs were 0.39-2.38 ng/L and 0.91-6.05 ng/L respectively. Compared with the water quality of other regions, the concentrations...
Nowadays, endocrine disruptor compounds in the water system have become a concern due to the risk of contamination to wild life and humans even at the nanogram level. Excess estrogens and androgens are a major contributor group of endocrine compounds. Statistical surveys have shown that dairy farms contribute to over 90% of the total estrogens in the UK and US. An analytical system is being developed...
Soil pollution is a worldwide problem. Both inorganic and persistent organic pollutants (POPs) possess high toxicity and long-term persistence. Biosurfactant based remediation technologies for contaminated soil are of increasing importance recently, and they have been demonstrated to be effective in uptaking both heavy metals such as Cd, Pb, Zn, Cu, and organic pollutants like hydrophobic organic...
Endocrine Disruptors, which is trace but more and more noted in aquatic environment, has a significant effect on people's hormone systems. The estradiol (E2) was a research object, and the effects of solution parameters (concentration, pH, ionic strength and natural organic matter (NOM) ) on the retention of trace E2 by nanofiltration membrane (NF) (BDXN-90 polyamind aromatic compound membrane) filtration...
Trichloroethene (TCE), usually in the form of dense non-aqueous phase liquid (DNAPL), is a widely used degreasing ingredient causing profound soil and groundwater contamination. While bio-enhanced dechlorination of TCE to harmless Ethene is a promising technique for waste water treatment, the mechanism and related phenomenon have not been thoroughly understood, especially in groundwater. A comprehensive...
Soil slurry reactor technology is one of the effective methods for treating PAHs contaminated soil. In this paper, removal of high molecular weight PAHs, Indeno (1,2,3-cd) pyrene (Inp), was studied in soil slurry reactors with isolated bacteria from PAHs contaminated soil. The factors affecting Inp biodegradation and the optimal conditions were investigated using orthogonal experimental design (L9(34))...
A novel method extracting with ether, deriving by methanol, deteminating with gas chromatography-mass spectrometry (GC-MS) for analyzing 8 kinds of acid herbicide residues in water has been established. The optimum experimental conditions were as follows: Adding 8 drops of concentrated sulfuric acid; adding 1.0 mL methanol; deriving 60.0 min. Linear of all herbicides is good in the range of 0.05 to...
PFCs are used as surfactants and lubricants in industrial production and have caused global environmental pollution. In recent years, a lot of toxic actions have been found, such as hepatotoxicity, immunotoxicity, reproductive toxicity, which posed a serious threat to human health. Data of perfluorooctanoate (PFOA) and perfluorooctanesulfonate (PFOS) in water samples, including coastal water, surface...
For make full rational use of the packed media surface, the fluent software was used to the section area of the bio-trickling filter's inlet is enlarged and the outlet gradually converged. The enlarged cross-flow bio-trickling filter is characterized with low pressure drop and uniform distribution of gas and spray liquid. The filter inoculated with efficient Pseudomonas putida on the ceramic pellets...
