Abstrak. Limbah pewarna industri tekstil merupakan limbah cair yang sulit teroksidasi dan berbahaya bagi lingkungan. Radikal hidroksil (•OH) merupakan spesies yang sangat efektif dalam mengoksidasi berbagai limbah cair organik seperti limbah pewarna.  Metode Elektrolisis Plasma sangat produktif menghasilkan radikal Hidroksil sehingga efektif dalam menyisihkan (mendegradasi) berbagai jenis limbah pewarna tekstil seperti Remazol Red. Penelitian ini bertujuan mengoptimalkan proses degradasi remazol red RB 133 dan konsumsi energinya menggunakan metode Elektrolisis Plasma melalui pengaturan suhu dan  injeksi gelembung  udara dalam larutan. Pembentukan H2O2 merupakan indikator pembentukan •OH pada reaksi Elektrolisis Plasma. Injeksi udara pada larutan limbah pewarna menurunkan arus listrik pada kurva karekateristik arus-tegangan. Kenaikan suhu larutan dari 45 oC menjadi 75 oC  selama 10 menit reaksi tampa injeksi udara menurunkan konsumsi energi  dari 229,9 kJ menjadi 219,5 kJ serta menurunkan  produksi H2O2 dari 4,8 mmol menjadi 3,1 mmol. Sementara injeksi udara pada suhu 75 oC selama 10 menit proses menurunkan konsumsi  listrik hingga 28,5% dan meningkatkan produksi H2O2 hingga 27,3 %. Namun demikian injeksi udara hanya meningkatkan degradasi Remazol Red sebesar 1,8 %.  Suhu optimum dicapai pada 55oC, dengan produksi H2O2 sebesar 5,7 mmol selama 30 menit. Injeksi udara udara mampu meningkatkan efektivitas proses. Hasil penelitian menunjukkan persen penyisihan mencapai 88,9% dengan  konsumsi energi sebesar 115,2 kJ dalam waktu 30 menit reaksi. Kata kunci: elektrolisis plasma, remazol red, gelembung udara. Abstract. Effect of Temperature and Air Injection on Degradation of Remazol Red Textile Dyes by Plasma Electrolysis Method. The textile dye waste is a liquid waste that is difficult to oxidize and dangerous for the environment. Hydroxyl radicals (• OH) are very effective species in oxidizing various organic liquid wastes such as Remazol Red. Plasma Electrolysis Method is very productive in producing Hydroxyl radicals, resulting in effective degradation of various types of textile dye waste such as Remazol Red. This study aims to optimize the degradation process of remazol red RB 133 and its energy consumption using the Plasma Electrolysis method through temperature regulation and injection of air bubbles in solution. The formation of H2O2 is used an indicator of the formation of •OH in the Plasma Electrolysis reaction. The Air injection decreases the electric current on the current-voltage characteristic curve. The solution temperature increases from 45oC to 75oC for 10 minutes reaction without air injection were able to reduce the energy consumption from 229.9 kJ to 219.5 kJ and H2O2 production from 4.8 mmol to 3.1 mmol. Meanwhile, the addition of air injection at 75oC within 10 minutes of reaction were able to reduce electricity consumption by 28.5% and increases H2O2 production by 27.3%. However, the addition of air injection only increased the degradation of Remazol Red by 1.8%. The optimum temperature was reached at 55oC, with H2O2 production of 5.7 mmol for 30 minutes. The addition of air injection has been shown to increase the effectiveness of the process. The results showed degradation percentage reached 88.9% with energy consumption of 115.2 kJ within 30 minutes of reaction. Keywords: air injection, plasma electrolysis, remazol red. Graphical Abstract

Electrolysis Method

Remazol Brilliant Blue is a dye waste mostly generated by the textile industry and can be very dangerous to the environment. Plasma electrolysis is a method that can produce hydroxyl radicals in large quantities in order to degrade the dye compounds. This study aims to test the ability of plasma electrolysis method to degrade Remazol Brilliant Blue wastewater using NaCl as electrolyte, with the addition of Fe2+ ion and air injection. Before the degradation process was carried out, permanganometric test was performed to see the production of hydroxyl radicals with the variations of electrolyte concentration and voltage. The degradation process were investigated more specifically by looking at the effect of Fe2+ ion concentration and the initial concentration of Remazol Brilliant Blue. Remazol Brilliant Blue degradation reached 98.5% in 30 minutes where the initial concentration of Remazol Brilliant Blue is 100 ppm, voltage of 750 V, NaCl concentration 0.03 M,with the addition of 40 ppm Fe2+ ion and air injection. The results show that plasma electrolysis with NaCl as electrolyte using air injection has a good potential in degrading dye wastewater in the environment.

Remazol Red

This research determined the optimum concentration of Fe2+ to degrade waste textile dye by Contact Glow Discharge Electrolysis (CGDE) method with air injection. The addition of Fe2+ ions can increase the degradation rate of the dye waste due to the radical catalytic conversion of H2O2 producing OH radicals that play a significant role in the degradation process. Remazol Red was used as a dye synthetic dye which was degraded using a batch reactor equipped with continuous cooling water. Experimental results showed that waste concentrations of 100, 200, 300 and 400 ppm obtained the optimum Fe2+ concentration at 10, 20, 30 and 40 ppm, respectively. The higher concentration of dye waste indicated the higher the Fe2+ ion requirement to decrease the textile dye waste.

Plasma Electrolysis

Plasma electrolysis has been proved have much higher effectivity in degrading complex pollutant contained in batik dye wastewater. This study aims to investigate the effect of gas bubbles with air injection of plasma electrolysis in decolorization process. A new method to form bubbles using injection of air directly through anode with a tiny hole of glass tube is proposed. This research work presents the effects of gas injection rates on various phenomena such as electrical power of discharge pulses, concentration of OH radicals, and the decolorization percentage of remazol red as the dye waste in a batch reactor system. Experimental results showed that direct injection of air through anode can reduce the required energy for plasma generation significantly compared to non gas injection. Energy consumption for discharge plasma was observed lowered at higher rates of gas injected. Optimum gas flow rate at different voltage has been evaluated based on the physical and chemical characteristics of plasma. At higher required energy due to higher operation voltage used, the required gas injection rate to effectively degrade the waste was found higher.
