ABSTRAK REDUKSI AKTIVITAS URANIUM DALAM LIMBAH RADIOAKTIF CAIR MENGGUNAKAN PROSES ELEKTROKOAGULASI.Limbah yang dihasilkan dari proses pengembangan bahan industri bersifat radioaktif yang mengandung uranium yang dapat menimbulkan dampak negatif pada manusia dan lingkungan. Pengolahan limbah radioaktif pada saat ini masih banyak menggunakan bahan-bahan kimia.Penambahanbahan kimiauntuk mereduksi bahan pencemar dinilai kurang efisien karena kurang ramah lingkungan, memerlukan waktu yang lama, dan biaya yang mahal. Untuk itu akan diterapkan metode proses elektrokoagulasi untuk menurunkan aktivitas uranium dari larutan limbah cair. Tujuan penelitian ini adalah untuk mengetahui efisiensi penurunan aktivitas uranium dalam limbah radioaktif cair yang dihasilkan pada proses elektrokoagulasi dengan variasi tegangan, waktu tinggal, jarak elektroda dan pH inlet limbah. Limbah simulasi yang digunakan memiliki kadar kontaminan uranium sebesar 500 mg/L. Percobaan ini dilakukan dengan metode batch dengan elektroda aluminium. Hasil penelitian diperoleh parameter optimal pada tegangan 12,50 V, jarak 1 cm, pH 7, dan waktu proses selama 60 menit diperoleh efisiensi penurunan limbah uranium sebesar 97,20 %.Kata Kunci:elektrokoagulasi, reduksi limbah uranium, tegangan, aluminium.

“…Oxidation by ozone, super-iron (VI) and hypochlorite were the most efficient treatment methods, but they are less preferable due to the operating cost and the generation of a second pollution resulting from the presence of residual chlorine [10,11]. In recent years, electrocoagulation has shown its efficiency to treat the several dye waste [12][13][14][15][16][17]. The electrocoagulation (EC) technique using iron or aluminum anode is an electrochemical process that was developed to overcome the drawbacks of conventional treatment techniques [18][19][20][21].…”

The performance of the electrocoagulation treatment of synthetic food dye waste industry was studied using iron anode. The influence of several parameters as electrolysis current, chloride concentration, electrolysis time and pH was investigated. In order to verify these factors and their impact on the discoloration efficiency, an experimental design model was established. The mathematical model was created using a rotatable, uniform and central composite design. This model described the color removal efficiency and the energy consumption according to the studied parameters. The graphical representation of the model according to the parameters allowed us to define optimal treatment conditions. The optimal values of electrolysis current, chloride concentration, electrolysis time and pH were respectively 14.4 mA/cm 2 , 5.76 g/L, 39 mn and 7. 94.52% of color removal efficiency is achieved with an energy consumption of 3.90 KWh/m 3 .

“…A thorough classification of treatment strategies for different targets is presented in [11]. From this categorization and due to various other reports, it can be seen that electrochemical treatment is a popular method that is used particularly for food production wastewaters [1][2][3][4]. The pollution sometimes requires careful treatment of a particularly harmful material.…”

Abstract. Electrochemical treatment of wastewaters that are rich in organic compounds is a popular method, due to its acidic nature that avoids biological treatment. In many cases, the pollution hazard is considered as the chemical oxygen demand (COD) from active carbon, and the success of the treatment is measured in terms of how much this specific parameter is reduced. However, if electricity is used during the treatment process, the treatment "itself" has manufacturing and operational energy costs. Many of the studies consider energy utilization as a monetary cost, and try to reduce its amount. However, the energy cost of the treatment also causes emission of carbon at the energy producing side of the closed loop. This carbon emission can be converted into oxygen demand, too. Therefore, it can be argued that one must look for the total optimal carbon efficiency (or oxygen demand), while reducing the COD. We chose a highly acidic wastewater case of vinegar production, which is a popular food product in Turkey, to demonstrate the high energy consumption and carbon emission problem of the electrochemical treatment approach. A novel strategy is presented to monitor total oxygen demand simultaneously at the treatment and energy production sides. Necessity of renewable energy utilization and conditions on process termination points are discussed.
