Preparation of TiO2 photocatalyst with the matrix of palm wood (Arenga pinnata) waste in the photodegradation of batik wastewater

The study aimed to the preparation of TiO2 photocatalyst with the matrix from palm wood waste whose has lignin and cellulose content. TiO2 photocatalyst with the matrix from the wastewater of palm wood waste (TiO2/pww) was used as photocatalyst in photodegradation of batik wastewater. TiO2 solid was dissolved in ethanol and aquadest, added with the powder of wood palm waste and stirred with a magnetic stirrer for 16 hours. Then separation was carried out using buchner and filtrate and residue were obtained. The filtrate was disposed and the residue was calcined with various temperatures for 3 hours. The temperatures in this research were 100 degrees C (TiO2/pww-100); 200 degrees C (TiO2/pww-200); 300 degrees C (TiO2/pww-300). Analysis and characterization of TiO2/wwp were conducted using X-ray diffraction (XRD) and spectrophotometer Fourier Transform Infra Red (FTIR) methods. Photocalalytic TiO2/wwp use the batch system in a reactor with UV light 40 watts, 220 volts and length wave 360 nm the plate magnetic stirrer. Liquid waste batik adds TiO2/wwp with time variation. At XRD analysis showed that the preparation of TiO2/pww could be done on the heating TiO2/pww temperature of 100 degrees C and 200 degrees C. At the temperature of 300 degrees C, it was indicated that the lignocelluloses in palm wood waste were burned, meaning that few lignocelluloses remained. The result of FTIR analysis showed clearly that at the temperature of 300 degrees C, a few spectrum of lignocelluloses remained in palm wood waste, while at a temperature of 100 degrees C and 200 degrees C, spectra of lignocelluloses of palm wood waste remained. The result of photocatalysis test indicated that TiO2/pww could reduce 40%, 72%, 81% and 64% COD for TiO2 (control), TiO2/pww-100, TiO2/pww-200 and TiO2/pww-300, respectively.
