Abstract	Untreated arsenic polluted groundwater is threatening people health, especially the people in rural areas. Soil may become one kind of promising natural material applied conveniently in rural areas for the treatment of arsenic polluted groundwater, due to its abundance, low cost, and high adsorption efficiency. The present study investigated arsenic(V) (As(V)) adsorption on two red soil samples weathered from granite (RSG) and sandstone (RSS). The two soil samples contain similar mineral types but show relatively high differences of content of iron, aluminum, and organic matter (OM), as well as point of zero charge (pH$_{PZC}$) and specific surface area (SSA). Batch experiments were performed to examine the effect of initial As(V) concentration, solution pH, and temperature on the kinetics of the adsorption of As(V) by the two soil samples. The experimental results showed that the As(V) adsorption onto the two soil samples was influenced by the physicochemical properties of the soils, especially the content of iron and aluminum, the OM, as well as the pH$_{PZC}$, and chemisorption was the main adsorption mechanism. The RSG sample with higher content of iron and aluminum and pH$_{PZC}$ showed relatively high adsorption efficiency. The OM played a negative role in the adsorption process, especially as the As/Fe molar ratio is higher. Higher adsorption capacities for the two soil samples were both obtained at lower initial As(V) concentration (1.50 and 4.0 mg/l), lower pH value (5.0), and higher temperature (313 K). Comparing to the RSS, the RSG is more suitable for the treatment of As(V)-polluted groundwater. Considering the experimental results and the natural conditions, the suggested operational conditions are pH around 7.0, temperature 293–303 K, As(V) concentration less than 4.0 mg/l, and hydraulic retention time no less than 180 min.
