“…Elektrokoagülasyon (EK), reaktör içine yerleştirilen bir anot elektrot ile doğrudan elektrik akımının uygulandığı ve koagulant iyonlarının (Al +3 , Fe +3 , Fe +2 ) oluştuğu elektrokimyasal bir tekniktir [12]. Son araştırmalar, EK prosesin pek çok avantajı sebebiyle yukarıda bahsedilen konvansiyonel yöntemlere kıyasla daha alternatif verimli bir teknoloji olduğunu göstermiştir [13], [14]. Su ve atıksulardan florür giderimi üzerine yapılmış fazla sayıda çalışma [15]- [18] olmasına rağmen, izoterm ve kinetik modelleme üzerine yapılmış çalışma sınırlı sayıdadır.…”

Bu çalışmanın ana amacı, alüminyum elektrotlar kullanılarak elektrokoagülasyon tekniği ile sulu çözeltilerden florürün giderilmesidir. Çalışma koşullarını optimize etmek için akım yoğunluğu, zaman ve giriş florür konsantrasyonu gibi çeşitli parametrelerin etkisi üzerine çalışmalar yürütülmüştür. Deneysel çalışmalar, 11 mA/cm 2 akım yoğunluğu, 30 dk reaksiyon süresi ve 10 mg/L giriş florür konsantrasyonu koşullarında %87,4 maksimum giderim veriminin elde edildiğini göstermiştir. Elektrokoagülasyon mekanizması ve prosesin karakteristik parametreleri isoterm (Langmuir and Freundlich) ve kinetik modeller (1. ve 2. Derece) ile analiz edilmiştir. Deneysel veriler Langmuir ve Freundlich izoterm denklemleri ile uyum sağlamıştır. Kinetik çalışma sonuçları, farklı koşullar altında 2. derece kinetik modelin daha yüksek korelasyon katsayısı sağladığını göstermiştir.The main objective of the present study was the removal of fluoride from aqueous solution by electrocoagulation technique using aluminum electrodes. The effect of various parameters such as current density, time and initial fluoride concentration were studied to optimize the conditions. Experimental study showed that maximum removal efficiency (87.4%) was achieved at the conditions of current density 11 mA/cm 2 , reaction time 30 min and initial fluoride concentration 10 mg/L. Isotherm models (Langmuir and Freundlich) and kinetic models (pseudo-first order and pseudo-second order) were used to analyze the electrocoagulation mechanism and characterize the process parameters. Experimental data well fitted with Langmuir and Freundlich isotherm equations and results of the kinetic study indicated that pseudo-second order kinetic model give higher correlation coefficients for different conditions.

The focus of this study is purifying the wastewater from the lacquers and paint industry in Western Romania, containing different organic compounds.The organic load in wastewater is found in the form of various organic compounds. Nonpolar organic substances lighter than water form a layer that blocks the flow of oxygen necessary, while polar substances are soluble in water and can be toxic to the fauna or create the effect of eutrophication causing disequilibrium in the biotope.In this paper we aimed at eliminating these organic compounds from wastewater by physical-electrocoagulation and chemical-oxidation methods to ensure a high degree of removal of these compounds to discharge into the sewage. The wastewater was characterized before and after the treatment following a series of quality indicators (chemical oxygen demand COD, total organic carbon TOC, lead Pb(II), cadmium Cd(II), chrome total Crtot, copper Cu(II), nickel Ni(II), zinc Zn(II), manganese Mn(II)). The total organic carbon analysis (TOC) was performed before and after the treatment to determine the total content of organic compounds.The resulting sludge from the wastewater contaminated with organic compounds treatment was subjected to thermal analysis.
