Decolorination and microorganism degradation from biodeinking waste using flow system of photoelectrodegradation


Degradation process results fotoelektrokalatalik from waste of biodeinking with photoanoda Ti / TiO2-NiO with flow system had been achieved. This research aims to study the activity of photoanoda TiO2 / NiO on waste photoelectrocatalitic degradation of dyes and the number of microorganisms biodeinking. Preparation photoanoda Ti / TiO2-NiO done with the technique of wet impregnation, then composite TiO2-NiO sprayed on the surface of the electrode Titanium. Photoanoda characterization is done by X-Ray Diffraction (XRD), fourrier Transform Infra Red (FTIR) and TEM-SEM .. XRD diffractogram TiO2-NiO composite showed characteristic peak of TiO2-NiO at 2θ = 33o . NiO existence characterized by FTIR absorption Ni-O at 412.77 cm-1. Meanwhile, TEM and SEM analysis showed TiO2 with crystal size in the region of 50 nm on the surface of Ti plate. Fotoelektokatalitik degradation dye waste results biodeinking done using photoanoda Ti / TiO2-NiO and Ti cathode using a halogen lamp 300 W / m2 . Results of the maximum degradation of dye wastewater biodeinking results shown in the voltage 6 volts with a flow rate of 3 mL / sec with% 90.10% decolorination reached. While the number of bacteria content analysis was performed using the method PJB (Calculation of Total Bacteria) with optimum results on the bacterial degradation of voltage 6 volts.
