The mercapto group (thiol, -SH) is one of the most important functional group of ligands, particularly 3-mercaptopropyl-trimethoxysilane (MPTMS), which has relatively high affinity to bind heavy metal ions. The present study was aimed to synthesize and characterize graphene oxide (GO) modified with the MPTMS via silanization step. The effect of an initial concentration of the MPTMS (0.8-14.4% w/v) was experimentally optimized. Then, the obtained GO-MPTMS product was characterized by Fourier Transform infrared spectroscopy (FTIR) and energy dispersive X-ray spectroscopy (EDX) techniques. From the results, the optimum conditions for the GO-MPTMS production were 4.8% w/v MPTMS at 65C for 6 h. It exhibits the IR characteristic peaks at wave numbers (cm-1) of 3367 (O-H), 2576 (S-H), 1719 (C=O), 1224 and 1049 (C-O), and 1160 (Si-O-C) indicating their functionalized GO-MPTMS. While EDX of this material reveals both Si and S spectra, also indicating the MPTMS bound on the surface of GO. It could, therefore, be implied that the GO-MPTMS was successfully obtained for further applications.
