Abstract (English)

F-TiO2/AC was synthesized using sol-gel method. The structure and composition of these materials were analyzed using various techniques, including scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX), X-ray diffraction (XRD), and Fourier transform infrared spectroscopy (FT-IR). The morphological properties of the artificially manufactured F-TiO2/AC substance were found to be amorphous, rough, and clustered with the eleme nts titanium, carbon, oxygen, and fluorine. Its mean particle size is 8.67 nm, and its standard deviation is 0.41 nm. Furthermore, the results of the FTIR on F-TiO2/AC discovered that peaks belonging to various functional groups such as hydroxyl, carboxylic acid, alkyl groups, and carbonyl groups conform to the functional groups that are present in the sample.

The study also investigated the effects of pH, photocatalyst loading, and irradiation time on the removal efficiency. The researcher examined the percent removal of benzene, toluene, and xylene using Response Surface Methodology (RSM) and Central Composite Design (CCD) to optimize the process. The RSM approach, which is a statistical modeling technique, was employed to analyze the experimental data and determine the optimal conditions for maximizing the removal of these volatile organic compounds. The obtained parameters for percent removal of BTX, benzene (93.036%), toluene (98.327%) and xylene (98.466%) were as follows: pH of the solution (5.759), catalyst loading (3.47 g/L of solution), and irradiation time (4.233 hours).

In summary, the synthesized F-TiO2/AC was proven to have a high photocatalytic activity for the degradation of petroleum organic pollutants (BTX). This study successfully developed a simple and effective method to resolve issues concerning petroleum wastewater.

Abstract (Filipino)

Ang F-TiO2/AC ay sinintetisa gamit ang sol-gel method. Ang istraktura at komposisyon ng mga materyales na ito ay sinuri gamit ang iba't ibang mga pamamaraan, kabilang ang scanning electron microscopy (SEM), energy-dispersive X-ray analysis (EDX), X-ray diffraction (XRD), at Fourier transform infrared spectroscopy (FT-IR).

Ang mga katangian ng morpolohiya (morphological properties) ng artipisyal na ginawang substansya ng F-TiO2/AC ay natuklasang walang tiyak na hugis (amorphous), magaspang (rough), at nakakumpol (clustered) kasama ang mga elemento ng titanium, carbon, oxygen, at fluorine. Ang mean particle size nito ay 8.67 nm, at ang standard deviation nito ay 0.41 nm. Bukod pa rito, ang mga resulta ng FTIR sa F-TiO2/AC ay natuklasan na ang mga peak na nauukol sa iba't ibang functional groups gaya ng hydroxyl, carboxylic acid, alkyl groups, at carbonyl groups ay umaayon sa mga functional groups na naroroon sa sample.

Sinuri rin ng pag-aaral ang mga epekto ng pH, dami ng photocatalyst loading, at oras ng pag-iilaw (irradiation time) sa removal efficiency. Sinuri ng mananaliksik ang porsyento ng pagtanggal (percent removal) ng benzene, toluene, at xylene gamit ang Response Surface Methodology (RSM) at Central Composite Design (CCD) upang i-optimize ang proseso. Ang RSM approach, na isang pamamaraan ng statistical modeling, ay ginamit upang suriin ang datos ng eksperimento at tukuyin ang optimal conditions para ma-maximize ang pagtanggal ng mga volatile organic compounds na ito.

Ang nakuwang mga parameters para sa porsyento ng pagtanggal (percent removal) ng BTX, benzene (93.036%), toluene (98.327%) at xylene (98.466%) ay ang mga sumusunod: pH ng solusyon (5.759), catalyst loading (3.47 g/L ng solusyon), at irradiation time (4.233 hours).

Bilang pagbubuod, ang sinintetisa na F-TiO2/AC ay napatunayang may mataas na photocatalytic activity para sa pagdegrade (degradation) ng petroleum organic pollutants (BTX). Matagumpay na nakabuo ang pag-aaral na ito ng isang simple at epektibong pamamaraan upang lutasin ang mga isyu tungkol sa petroleum wastewater.
