Abstract
Reaktor fotokatalisis untuk degradasi warna limbah cair pada industri tekstil memiliki beberapa jenis salah satunya fotoreaktor kaskade, namun reaktor tersebut tidak dilengkapi dengan alat ukur tingkat degradasi zat warna tekstil. Penelitian terkait perancangan reaktor fotokatalisis telah dilakukan dengan tujuan untuk merancang reaktor fotokatalisis yang mengukur fotodegradasi secara realtime, mengetahui konsentrasi TiO2 yang optimal dalam pendegradasian Methylene Blue (MB) dan membandingkan hasil degradasi MB dengan katalis dan tanpa katalis. Pada penelitian ini digunakan sensor photodiode untuk mengukur fotodegradasi methylene blue secara langsung pada reaktor. Adapun variasi perlakuan berupa reaktor kontrol (tanpa katalis) dan reaktor dengan katalis 2 ± 0,005 gr, 3 ± 0,005 gr serta 4 ± 0,005 gr yang dideposisi pada substrat kaca dengan perekat vernis. Pengujian fotodegradasi dilakukan dengan menggunakan spektrofotometer UV-Vis dan sensor fotodegradasi. Dari penelitian tersebut dapat diketahui reaktor fotokatalisis yang dilengkapi dengan alat ukur tingkat degradasi secara realtime dapat berjalan dengan baik. Adapun penurunan nilai absorbansi Methylene Blue pada reaktor kontrol, reaktor berkatalis TiO2 2 ± 0,005 gr, 3 ± 0,005 gr, dan 4 ± 0,005 gr berturut-turut adalah 4,84% ± 0,0005, 61,8% ± 0,0005, 89,8% ± 0,0005, dan 76,1% ± 0,0005. ============================================================================================================================
The photocatalytic reactor to degrade liquid waste in the textile industy has several types of one from the cascade photoreactor, but this reactor is not equipped with a degradation level measuring instrument for textile substances. Reasearch related to the design of photocatalytic reactor has been carried out with the aim of designing a photocatalytic reactor that measures photodegradation in realtime, knowing the optimal concentration of TiO2 in the degradation of Methylene Blue (MB) and comparing the result of MB degradation with catalyst and without catalyst. In this study, a photodiode sensor was used to measure the photodegradation of textile dyes directly to the reactor. The treatment variations in the form of a control reactor (without catalyst) and reactor with catalysts of 2 ± 0,005 gr, 3 ± 0,005 gr, and 4 ± 0,005 gr were deposited on a glass substrate with vernis. photodegradation testing was carried out using a UV-Vis spectrophotometer and photodegradation sensor. From this research, its can be seen that the photocatalytic reactor equipment with a degradation level in realtime can run well. The decrease in absorbance value of Methylene Blue in control reactor, TiO2 catalyst reactor 2 ± 0,005 gr, 3 ± 0,005 gr, and 4 ± 0,005 gr respectively were 4,84% ± 0,0005, 61,8% ± 0,0005, 89,8% ± 0,0005 and 76,1% ± 0,0005.
