Gen. Dato' Prof. Dr. Nano-tube Hydrophobic Cyanex 272 Solid-phase extraction Malaysian Technical Universities Conference on Engineering and Technology (MUCEET) Malaysian Technical Universities Conference on Engineering and Technology organized by Universiti Malaysia Pahang in collaboration with Universiti Tun Hussein Onn Malaysia, Universiti Teknikal Malaysia Melaka & Universiti Malaysia Perlis on June 20th - 22nd, 2009, at MS Garden Hotel, Kuantan, Pahang, Malaysia. This paper reports on the synthesis and application of hydrophobic silica nano-tubes immobilized with Cyanex 272 (HBSNC) as a new, inexpensive and easily prepared solid-phase extractant for the extraction of Cu(II), Ni(II) and Zn(II) from aqueous solution. The extraction had occurred due to the complexation of metal ions with Cyanex 272 in silica tubes. For the preparation of silica nano-tubes template method and to make these tubes hydrophobic co-precursor method with ambient drying was used and finally Cyanex 272 was immobilized with these nanotubes. Hydrophobicity of silica nano-tubes were evaluated by washing the tubes with water and studied the extraction performance of both materials of before and after wash as a function of pH of aqueous solution and metal ion concentration. The extraction performance was almost the same before and after washing. The maximum extraction capacity of hydrophobic nano-tubes was found to be 0.35 mmol/g 2010-08-13T01:33:20Z 2010-08-13T01:33:20Z 2009-06-20 Working Paper p.1-3 http://hdl.handle.net/123456789/8643 en Proceedings of the Malaysian Technical Universities Conference on Engineering and Technology (MUCEET) 2009 Universiti Malaysia Pahang |
