ABSTRACT

The production of silica using rice husk as the main material in this research has
been done. The silica that produced was characterized using Scanning Electron
Microscopy (SEM/EDS) to determine the surface morphology, Particel Size
Analizer (PSA) to determine the distribution of particle size, and Fourier
Transform Infra Red (FTIR) to indentify the functional group. The adsorption test
was conducted for determination of optimum mass of adsorbent, the time of
optimum contact, the optimum pH, the determination of initial concentration, the
adsorption kinetics, and the adsorption isotherm of phenantherene. The result of
mass of adsorbent optimum was obtained on 3 mg, the time of optimum contact
was obtained on 120 minutes, the optimum pH was obtained on pH 3, and the
initial concentration phenantrene was obtained on 15 mg L-1. The adsorption
kinetics data of phenanthrene on silica matchs with the model of pseudo second
order with the correlation coefficient (r2) is 0,9997. The adsorption isotherm of
phenanthrene on silica follows the Freundlich isotherms with the correlation
coefficient (r2) is 0,975 suggesting the type of the physical adsorption.
Keywords: rice husk, silica, adsorption, Polycyclic Aromatic Hydrocarbon (PAH),
