“…Este cromo le da la tonalidad al colorante. La levadura Saccharomyces cerevisiae se ha reportado como capaz de biorremediar colorantes [3], [16], [17], [18]. La levadura S. cerevisiae tiene enzimas azoreductasas que catalizan compuestos en presencia de varias coenzimas reductoras como FADH2, NADH y NADPH, mostrando su versatilidad y su potencial uso como agente degradador de colorantes [13], y gracias a su complejo enzimático se utiliza en otros procesos [19].…”

(Tipo de Artículo: Investigación científica y tecnológica. Recibido: 16/08/2017. Aprobado: 11/12/2017) IntroducciónUno de los mayores problemas a nivel ambiental es la contaminación de las aguas por vertimiento de contaminantes de diferente índole [1]. Las empresas textiles y de teñido utilizan grandes cantidades de colorantes. El proceso de tinturado no es completamente eficiente, porque un porcentaje de los colorantes es vertido en las aguas residuales de estas Resumen. La presencia de aguas residuales coloreadas evita la penetración de la luz a las aguas, disminuye la fotosíntesis de plantas, la supervivencia de organismos acuáticos, y afecta significativamente el paisaje. Se optimizó la geometría del colorante Negro P-SG y del complejo cromado, con el fin de proponer los enlaces susceptibles de rompimiento por las enzimas que contiene la levadura Saccharomyces cerevisiae inmovilizada en gelatina. El enlace azoico es la zona más susceptible de rompimiento por las enzimas, lo que produciría la disminución del color. El análisis cinético mostró que la KM es menor en la levadura inmovilizada, y la cinética de biorremediación del colorante es dependiente de su concentración. Las ecuaciones cinéticas de biorremediación son exponenciales de decrecimiento, y el tiempo de vida media de biorremediación del colorante es 0.67 hr a concentraciones máximas de levadura inmovilizada en relación al control. La ósmosis del colorante a través de la gelatina es dependiente de la concentración del colorante, por lo tanto, la biorremediación del colorante es dependiente de la concentración de colorante y de la concentración de levadura inmovilizada. En este trabajo se mostró la levadura inmovilizada en gelatina como una potencial herramienta para remediar colorantes azoicos. Abstract. The presence of colored wastewater prevents the penetration of light into the waters, decreases the photosynthesis of plants, the survival of aquatic organisms, and significantly affects the landscape. The geometry of the Black P-SG dye and the chromed complex was optimized, in order to

“…The equilibrium constant may be expressed in terms of enthalpy change as a function of temperature [46,47]. The temperature of solution was varied in the range of [18][19][20][21][22][23][24][25] C while all other parameters were kept constant. The maximum biosorption efficiency was achieved at 25 C (See Figure 11).…”

, and Co 21 ions onto Aureobasidium pullulans biomass was studied in batch procedure. The extents to which the experimental variables such as pH, contact time, stirring rate, and temperature affect the efficiency of biosorption were examined. The optimum values of pH (pH 5 5), amount of biomass, and contact time (1 day) were found to be 5.0, 1 g, and 24 h, respectively. The equilibrium data were fitted to the Langmuir and Freundlich isotherm models. The Freundlich model showed better (q 5 75-82 for different metal ions and R 5 1) fit and thus it was more suitable for the interpretation of experimental equilibrium data for Pb

“…Deneysel sonuçlara göre metilen mavisi gideriminde, en uygun çözelti pH'ı 7 olarak belirlenmiştir. Çözeltinin pH'ının 7'yi geçmesi durumunda ise metilen mavisi tutunma miktarında gözlemlenen azalma, farklı biyosorbentler ile yapılan benzer çalışmalarda da göze çarpmaktadır [9,10]. Metilen mavisinin pH 7'den sonraki artan pH değerlerinde gideriminin azalması ise biyosorbent yüzeyinde bulunan fonksiyonel grupların çözeltiye geçerek, yüzey özelliklerini değiştirmesi ve yüzeyde pozitif yüklenmiş bölgelerin oluşmasından kaynaklanmaktadır [11].…”

ÖZETYapılan bu çalışmada tarımsal bir atık olan nohut samanı, sulu çözeltilerden boyar madde gideriminde biyosorbent olarak değerlendirilmiştir. Çözelti pH'ı, biyosorbent miktarı, başlangıç boyar madde derişimi, temas süresi ve çözelti sıcaklığının biyosorpsiyon işlemine olan etkileri incelenmiştir. Ayrıca, metilen mavisi biyosorpsiyonuna ait denge izoterm, termodinamik ve kinetik çalışmalar gerçekleştirilmiştir. Biyosorpsiyon denge verilerinin Freundlich izotermi ile uyumlu olduğu belirlenmiş, biyosorpsiyonu en iyi ifade edebilen kinetik modelin ise sözde(yalancı) ikinci dereceden model olduğu saptanmıştır. Hesaplanan termodinamik parametreler, biyosorpsiyonun 20-50 °C aralığında kendiliğinden gerçekleşen endotermik bir işlem olduğunu göstermiştir. Metilen mavisi biyosorpsiyonu için nohut samanının maksimum tek tabaka biyosorpsiyon kapasitesi 108,7 mg/g olarak belirlenmiştir. Sonuç olarak, nohut samanının sulu çözeltilerden metilen mavisi gideriminde çevreye dost, düşük maliyetli ve etkili bir biyosorbent olarak kullanılabileceği belirlenmiştir.Anahtar Kelimeler: Biyosorpsiyon, boyar madde, nohut samanı, izoterm, kinetik, termodinamik EVALUATION OF FIELD DEBRIS OF CHICKPEA HUSK AS A LOW-COST BIOSORBENT FOR REMOVAL OF METHYLENE BLUE FROM AQUEOUS SOLUTIONS ABSTRACTIn the present study, an important agricultural waste, chickpea straw, was evaluated as biosorbent material for the removal of basic dyes from aqueous solutions. Effects of solution pH, biosorbent dosage, initial dye concentration, contact time and solution temperature on biosorption process were investigated. In addition, equilibrium, kinetic and thermodynamic studies were carried out for the methylene blue biosorption. It was determined that equilibrium data were in accordance with Freundlich isotherm and pseudo second order kinetic model was the best model to express the biosorption kinetics. Calculated thermodynamic parameters showed that, biosorption was a spontaneous endothermic process between 20 and 50 °C. The maximum monolayer biosorption capacity of chickpea husk was determined as 108.7 mg/g for methylene blue biosorption. As a result, chickpea straw could be used as an environmentally friendly, cheap and effective biosorbent material for the removal of methylene blue from aqueous solutions.
