In the present study, it was aimed to optimize the removal of reactive blue 19 dye by using peanut shells as a low-cost adsorbent. The influence of various process parameters namely pH (2,3 and 4), temperature (25, 35 and 45°C) and adsorbent amount (0.5, 1 and 1.5 g/100 mL) were studied using Box-Behnken design. According to the ANOVA results, the quadratic model with coefficient of determination (R2) value of 0.9984 and model F value of 487.80 was showed good fit of the experimental data to. Experimental conditions for optimum dye removal of 93.45% were determined as pH 2, 35°C and 1.5 g/100 mL adsorbent amount. Langmuir fitted better to the obtained equilibrium data for removal of reactive blue 19 than Freundlich and Temkin models. In addition, the adsorption kinetics was also studied for the reactive blue 19 removal onto peanut shell. The kinetic studies showed that the removal of reactive blue 19 fitted to pseudo-second-order model.

Sulu Çözeltilerden Yer Fıstığı Kabukları ile Reaktif Mavi 19 Giderimi: Cevap Yüzey Yöntemi ile Optimizasyonu

Öz

Bu çalışmada, reaktif mavi 19 boyarmaddesinin düşük maliyetli adsorban olarak yerfıstığı kabukları kullanılarak gideriminin optimizasyonu amaçlanmıştır. Box-Behnken tasarım yöntemi kullanılarak pH, sıcaklık ve adsorban miktarı parametrelerinin etkileri incelenmiştir. ANOVA sonuçlarına göre, regresyon analizi regrasyon katsayısı 0.9984 ve model F değeri 487.80 ile deneysel verilerin quadratik modele uygun olduğunu göstermektedir. Optimum boyarmadde giderimi (%93.45) için deneysel koşullar pH 2, 35°C ve 1.5 g/100 mL adsorban miktarı olarak belirlenmiştir. Reaktif mavi 19 giderimi için denge verilerinden Langmuir izoterminin Freundlich ve Temkin izotermlerinden daha uygun olduğu bulunmuştur. Ayrıca, yerfıstığı kabuğu ile reaktif mavi 19 giderimi için adsorpsiyon kinetiği incelenmiştir. Kinetik çalışmalar yalancı ikinci derece kinetiğe uyduğunu göstermiştir.
