Acrylpimaric acid ethylene glycol acrylate was used as the cross-linking agent to prepare rosin-based polymer microspheres through membrane emulsification-microsuspension polymerization. The prepared ...
Fluorescence analysis, being a non-invasive technique, has become one of the most powerful and widely used techniques for microbiologists and chemists to study various types of sample from photosynthe...
Street dusts collected from 20 sites as well as three special dust samples collected from chimney of coal-fired plant, smelter and refinery of nonferrous metals and automobile exhaust, respectively, i...
Polycyclic aromatic hydrocarbons (PAHs) were consistently documented in the sediments of the canals draining into Biscayne Bay. The study examines the contribution of urban runoff to PAHs discharges. ...
This manuscript describes an analytical method for the quantitative determination of 16-polycyclic aromatic hydrocarbons (PAHs) using accelerated solvent extraction (ASE), followed by purification on ...
Bioturbation by the burrowing crab Helice tiensinensis was investigated to determine its impact on polycyclic aromatichydrocarbon (PAH)-contaminated estuarine sediments. The concentrations of 16 U.S. ...
Desorption of pyrene and phenanthrene, from two charcoals and humic acid preloaded charcoals werestudied. Desorption occurred obviously in two fractions, with rapid and slow desorption rate constantra...
PM10 samples were collected at six sampling sites in city center of Tianjin from April 2008 to January 2009. The concentrations of 17 selected polycyclic aromatic hydrocarbons (PAHs) in PM10 were qua...
简要分析了多环芳烃(PAHs)的危害及水泵橡胶密封件中PAHs的来源,首次采用了水泵密封件中多环芳烃的超声萃取气相色谱-质谱(GC-MS)联用的测定方法。优化了超声萃取条件,确定了16种PAHs的分离和测定条件。样品经过超声波萃取,采用选择离子监测模(SIM)定性和定量检测水泵密封件中多环芳烃,用内标法对PAHs进行定量分析。用加标回收方法试验确定方法的准确度。结果表明:16种PAHs平均回收率为...
The degradation of three polycyclic aromatic hydrocarbons (PAHs), phenanthrene, pyrene and benzo[a]-pyrene in soils byPhanerochaete chrysosporium, andthe enzyme activities of lignin peroxidase (LiP) a...
Physical and chemical characteristics of particles from rubber-wood combustion in a natural rubber sheet smoking process were studied. Experimental parameters include wood moisture content and wood-b...
The presence of particle-associated polycyclic aromatic hydrocarbons (PAHs) was investigated in mixed residential/light industrial, industrial and commercial zones in summer 2000 and winter 2001 in T...
Sorption of three polycyclic aromatic hydrocarbons (PAHs, phenanthrene, anthracene and pyrene) on three charcoals and their pre-cursor substance(sawdust) was studied. The charcoals obtained by heating...
PM10 (particulate matter which passes through a size selective impactor inlet with a 50% efficiency cut-off at 10 μm aerodynamic diameter) and PM2.5 were collected at four sites (A: Xiaoping, B: Hul...
The characteristics of ambient particle-bound polycyclic aromatic hydrocarbons (PAHs) in the Angkor monument area of Cambodia were studied to evaluate the status of air pollution and the influence o...
