Efektivitas Adsorben Abu Layang Sisa Pembakaran Batubara Pada Pltu Pt. Best Untuk Menjerap Ion Logam Fe

SUMMARY
Fly ash resulting from burning coal in an electric steam power plant furnace is fine and pozolanic, produced in high volume every year. The main components of coal fly ash are silicate (SiO2), alumina (Al2O3), and iron oxide (Fe2O3). In this study, fly ash was used as an adsorbent which was activated by the chemical activation method using NaOH activator with various activator concentrations (0, 1, 3 and 5) M and physical activation at burning at 600oC for 2 hours. The fly ash adsorbent was characterized using Atomic Absorption Spectrophotometry (AAS) to analyze the chemical composition of the adsorbent and to determine the fly ash type according to ASTM C618, the fly ash type was type F obtained from the burning of anthracite and bituminous coal. Atomic Absorption Spectrophotometry (AAS) to analyze the chemical composition obtained the highest SiO2 content at 3M NaOH was 60.874%. Characterization using Fourier Transform Infrared Spectroscopy (FTIR) showed that the functional groups on fly ash adsorbent before and after activation had no differences such as Si-O-Si, Al-O-Al, O-Si-O, O-Al-O and OH. The results of 10 mgL-1 Fe metal ion adsorption with various concentrations of NaOH activator (without activation, 0M, 1M, 3M and 5M) for 60 minutes, stirring speed 100 was rpm, the efficiency of Fe metal ion reduction was 66.65%, 57.79%, 62.14%, 86.43% and 85.31%. The results of this study indicate that the optimum concentration of fly ash activator is the 3 M NaOH activator, and the moisture content is 0.35%. The adsorption mechanism of Fe metal ion in this study follows the Freundlich adsorption isotherm model.
