Removal of Iron From Produced Water Using Silica Adsorbent Material
The removal of Iron from produced water using adsorbent materials is taking a space of attention from the perspective of researchers. In this work, the characterization of chemically modified silica used as Iron ions adsorbent using Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), laser granularity instrument was performed. The point of zero charge (PZC) of modified silica was determined using titration method. Different parameters were used to better approach Iron removal. These parameters are 0.2 and 0.4 mg/l modified silica adsorbent dose, 30-180 min adsorption time and pH values of 4-10. The results showed that modified silica exhibited higher removal efficiency of Iron due to its surface characteristics. The results also showed that at 60 min adsorption time and pH 7, the maximum Iron removal efficiency with 99.99% and 99.98% was obtained using modified silica dose of 0.4 mg/l and 0.2 mg/l, respectively.
