Sintesis Fotokatalis Komposit Mno2-Bentonit Dengan Metode Sol-Gel Untuk Degradasi Limbah Cair Pabrik Kelapa Sawit

Palm oil mill effluent (POME) has a high organic content, dark brown in color,
has a upleasent smell, contains total suspended solids (TSS), Chemical Oxygen
Demand (COD), total dissolved solid (TDS) that exceed threshold set by
government regulation. POME is difficult to breakdown using biological
processes. Photocatalysis has been considered as a simple method to degrade
most organik pollutants if an effective catalyst is found. Metal oxides have been
often used as a catalyst for the degradation of organic contaminants since they are
much cheaper and have high catalytic activities. Among them, the MnO2 has
been proposed for the degradation a wide range of organic contaminants due to its
unique characteristics such as non-toxic, ease of preparation, various porous
structures and high catalytic activities. Here, the MnO2-bentonite composite was
synthesized using versatile sol-gel method and applied for the degradation of
POME.The X-Ray Diffraction and Gas Sorption Analyzer were used to
characterize the structure, phase, cristallinity and surface area of the composite.
The XRD results indicataed that the phase of manganese oxide in the MnO2-
Bentonite composite is the tunnel structure of cryptomelane-type manganese
oxide. Data from GSA experients indicated that the composite MnO2-bentonite
with 15% MnO2 content has the highest surface area and total pore volume
compared with those of MnO2-bentonite 5% and 10%. The degradation of POME
by the catalysts were studied by conducting the variation of reaction parameters
such as POME concentration, amount of MnO2 in the composite, composite mass,
and reaction time. The photocatalytic studies indicated that within 120 minutes
of reaction time, the COD concentration was reduced by 94,44% at a
concentration of POME 10:90, 15% MnO2 in composite , and 400 mg/L mass of
composite. The optimum condition of MnO2 in composite were also able to
reduce the concentration of TSS and TDS with the % efficiency of decreasing
respectively 86.38% and 25.26%. The optimum condition is even able to degrade
concentrated POME to fulfill COD threshold set by government regulation.
