• The phosphate sorption product on the clay fraction of Kanuma pumice (KP clay) after air-drying was revealed to be a material close to noncrystalline aluminum phosphate by infrared absorption (IR) spectroscopy. The IR spectrum of phosphate sorbed, obtained by subtracting the diffuse reflectance IR spectrum of KP clay from that of the phosphated KP clay, was close to that of noncrystalline aluminum phosphate. During the phosphate sorption reaction on KP clay, the amount of Cl^- sorption and the concentration of dissolved Al at the initial pH of 4.0 decreased with phosphate sorption. The amount of silicon released, that of Na^+ sorption and pH value increased with phosphate sorption. It was concluded that a part of KP clay, a short range order aluminosilicate, was converted to a material close to noncrystalline aluminum phosphate through phosphate sorption and release of silicon.
