Soils polluted by Chromite Ore Processing Residue (COPR) was sampled as study objects. Modified BCR sequential extraction procedure was adopt to analysis the chemical speciation of hexavalent chromium in the soils from Qingdao Hongxing Chemical Plant. The results show that, more than 80% of the total hexavalent chromium is the weak acid extractive speciation, and the water soluble speciation hexavalent...
Fluoride contamination transport and adsorption study is a hot subject of soil environment research. Dynamic adsorption, desorption and kinetics study can help us deeply understand the migration and transformation mechanism of fluoride in water and soil system, and provide theoretical basis for environmental assessment and treatment. This paper reveals the fluoride desorption law with the infiltration...
The properties of plant root exudates and their effects on the water solubility of PCP were investigated in this paper. The results showed that the hydrophobic and the high-molecular-weight fractions of sunflower(Helianthusannuus) root exudates were more than those of lucerne(Medicagosativa) root exudates. With time elapsed, the biodegradation rate of lucerne root exudates was higher than sunflower...
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)...
