To investigate the role and effects of the medium-grade phosphate rocks on Cu2+ removal in aqueous solution, three phosphate rocks (PRs) were selected from Hubei Province and the characteristics of Cu2+ removal were studied using batch experiment with phosphate rocks under different conditions in aqueous solution. The results showed: that the Cu2+ in aqueous solution was effectively removed by the...
The north most representative cinnamon soil was selected as the tested soil. The study considered the effect of dissolved organic matter on migration of Cu, Cd, Pb and Zn in soils by column experiment. Migration and transformation model was built which based on the soil solute transport model. It is important for the prediction of the temporal and spatial distribution of pollutant, and help to prevent...
A batch experiment was conducted to study the effect of pH and temperature on absorption and desorption of copper in soil, soil samples were collected from the vicinity of a copper tailings yard. The results showed that the pH value is one of the most important factors that influence the adsorption of copper. The Cu adsorption was reduced at the low pH. By increasing the pH value, the adsorption increased...
Abstract- Column experiment simulations were carried out to determine potential metal ion migration in order to establish the environmental impact of a manganese mine wasteland and to understand the transport dynamics of heavy metal migration by way of two different soil types (tailings and tailings mud) within the Xiangtan Manganese Mine wasteland. Simulations were conducted at the Research Section...
In this study, an isothermal batch experiment was conducted to assess the characteristics of adsorption of Zn and Cd in surface samples of three typical soils from Qingdao City, China. Sorption isotherms were characterized using Linear, Langmuir and Freundlich equations. The results indicated that all the sorption isotherms were well described by the Freundlich and Langmuir equations with high coefficients...
