The zirconium sulfate-surfactant mesoporous structured material(ZS) was synthesized by hydro-thermal synthesis. The material has regular hexagonal array of surfactant micelles and sulfate ion (HSO4-). We confirmed that sulfate ion in zirconium mesoporous structured material can be ion-exchanged with phosphate ion (H2PO4-) in phosphoric acid solution. On the X-ray diffraction (XRD) pattern of ZS, three peaks which shows the important characteristics of hexagonal crystal lattice were observed at (100), (110) and (200). The transmission electron micrograph (TEM) show high crystallization with pore size about 47Å. The maximum adsorption capacity of ZS was as great as 3.2 mmol-P/g-ZS. From the adsorption isotherm, correlation coefficients were higher for the Langmuir isotherm than the Freundlich isotherm. With the respect of chain length of surfactant, the adsorption capacity for phosphate synthesized with C12 was higher than C16 and C18. The highest amount of adsorbed phosphate on ZS was observed at the surfactant-to-zirconium molar ratio of 0.5 to 1. 한국물환경학회 지르코늄 메조기공 구조체의 합성조건 변화에 따른 인 제거 특성 Removal Characteristics of Phosphorus at Synthetic Variation of Zirconium Mesoporous Structure Article 2 한국물환경학회지, v.21, no.6, pp.637 - 642 한국물환경학회지 21 6 637 642 kci ART001132501 Mesoporous structure Phosphorus Ion exchange Adsorption Zirconium
