A study was conducted on the adsorption kinetics of diuron from aqueous solutions onto activated carbon fiber. The results showed that the formation of hydrogen bonds between diuron and water, and temperature variations may possibly affect the adsorption process. Furthermore, adsorption of diuron onto activated carbon fiber was affected remarkably by solution pH and the maximum adsorption amount was...
This paper studies the estimation of river pollutant discharge rate. With comprehensive analysis of primary factors impacting water quality, say pollutant concentration, water flow velocity, water discharge amount and natural degradation, we build an estimation model of river pollutant discharge rate based on one-dimensional water quality model. Considering that the distribution of waste outlets along...
On the basis of analysis of ash-water from Baoding power plant, chemical components of underground water and the condition of environmental hydrology the prediction on pollution from ash-water permeation was carried out by applying one- dimensional homogeneous mathematical model. The results show that ash-water will not take bad influence on the water quality of water source of Baoding city to ash-field...
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)...
