Nickel hydroxide (Ni) was calcined at 270 and 400 degrees C (denoted Ni270 and Ni400), and the properties of Ni, Ni270, and Ni400 were investigated. In addition, the phosphate adsorption capabilities of Ni, Ni270, and Ni400 were evaluated by examination of the effects of contact time and solution pH, analysis of an adsorption isotherm, and study of desorption. The amounts of phosphate ion adsorbed by the different samples showed the order Ni < Ni400 < Ni270. Finally, phosphate ions adsorbed onto Ni270 could be desorbed using sodium hydroxide, indicating that Ni270 can be used as a renewable adsorbent.
