- W2394211356 abstract "Arsenic can be adsorbed into soils by reaction with iron-containing minerals such as hematite. The As(Ⅲ) adsorption and desorption isotherms on the hematite(α-Fe2O3) surface were measured and the oxidation process was investigated,as a function of pH and temperature. The Langmuir equations describe the relationship of adsorption amount to the original concentration of As(Ⅲ) well(p0.05). The concentrations of As(V) (oxidized) in the solution increased but the oxidation rates decreased as the initial As(Ⅲ) concentration increased. Temperature is an important factor influencing both the adsorption and oxidation of As(Ⅲ) ion on the hematite surface. The adsorption amounts,adsorption rates,oxidation amounts and oxidation rates at 35℃ were all greater than those at 25℃,which suggested that higher temperature favored the adsorptive and oxidation reactions. This is also confirmed by the thermodynamic parameters ΔrGθmand ΔrHθ of the adsorption. The pH of the solution had different effects on the adsorption and oxidation of As(Ⅲ). The adsorption rates and amounts adsorbed were maximized at pH 8. However,the oxidation reaction rate and oxidation amounts both peaked at pH 6." @default.
