Abstract

This project is focuses on the development of APTES-functionalized MCM-41 as absorbent for nitrate removal. Cetyltrimethylammonium Bromide (CTAB) Tetraethoxysilane (TEOS), 3-aminopropyltriethoxysilane (APTES), sodium hydroxide (NaOH) and also water (H2O) will be used to synthesis MCM-41. Ammonium-functionalized silica MCM-41will be prepared by co-condensation method using 3-aminopropyltrithoxysilane (APTES) as amine-silica source. Different amount of APTES will be loaded into MCM-41 and its effect on nitrate removal will be studied. In order to study the structure and morphology of the materials, the resulting MCM-41 and amine-functionalized MCM-41 were characterized using different analytical methods. Based on the result of UV-VIS, it show the reduction of the nitrate concentration from the mixture of the absorbents MCM-41 and APTES-functionalized MCM-41 with potassium nitrate, KNO3 solution. The characterization results from the FTIR shows the bond between nitrate and hydrogen, carbon and carbon and lastly is carbon and bromide.
