Phosphorus adsorption on iron‐coated sand under reducing conditions
Journal of Environmental Quality, 2022 AbstractMitigation measures are needed to prevent large loads of phosphate originating in agriculture from reaching surface waters. Iron‐coated sand (ICS) is a residual product from drinking water production. It has a high phosphate adsorption capacity and can be placed around tile drains, taking no extra space, which increases the farmers’ acceptance.
