In order to overcome the above-mentioned negative effects, the fresh Chinese-fir shavings were extracted in KOH soultion, were analyzed by ZETA and SIZER to find out the leaching rule of nano particles in Chinese-fir wood. The results are as follows: (1) The extraction mass arrived at the maximum value when KOH concentration is about 17.5%. The micro/nano particles in Chinese-fir shavings would be...
To determination organic compounds in landfill leachates,the landfill leachates were extracted with a PT-C18 column and the extraction liquid were analyzed with a gas chromatograph coupled to an mass-selective detector(GC-MS). The results showed that total 162 kinds organic compounds been determinted out. One of them , there are 22 kinds of Chinese priority pollutants and 32 kinds united states environmental...
In order to overcome the above-mentioned negative effects, the extractives of the fresh Cunninghamia lanceolata shavings, which were obtained by using both the sorbitic-extracting approaches, were analyzed by ZETA and SIZER to find out the leaching rule of nano particles in Chinese-fir wood. The results are as follows: (1) The extraction mass arrived at the maximum value when NaOH concentration is...
Sustainable development is widely practiced by many engineers, academicians and policy makers for making the industries environmental friendly, to obtain sustainability in any industry there are many methods. Resources utilized in an industry should be identified properly in various processes and its utilization is to be optimized to increase the environmental performance of the industry. Ecomapping...
The extensive clayization of Dexing copper mine is responsible for water and soil pollutions because of the oxidation of sulfide minerals. During the clayization, harmful elements such as As, S, Sb and Pb could be effectively released into the clay and water. Using the abundant spectral information of short wave infrared (SWIR), combining with the spectral absorbed index, SAM (Spectrum Angle Mapper)...
