【 摘 要 】

It has been conducted magnetic material coating of iron sand with aminobenzimidazole through a sol-gel process. The magnetic material of iron sand is separated using an external magnet, then it is washed using aquades and Hydrogen Florida solution (HF) 10%. MM-Silica-Aminobenzimidazole (MMSABI) is characterized using a spectrophotometer Fourier Transform Infrared (FTIR), X-ray diffractometer (XRD), and Vibrating Sample Magnetometer (VSM). Moreover, it has been conducted pH acid test (1-6) to the stability by measuring dissolved ion Fe using Atomic Absorption Spectrophotometer (SSA) and the measurement of pH Point Zero Charge (pHpzc). The research result shows that the coating process of MMSABI through the successfulsol-gel process. Additionally, the aminobenzimidazol cluster enables specific interaction with metal iron with wastewater.
