Abstract

In this study, Brassica Napus straw was used as an adsorbent to eliminate Copper (II) from aqueous solution. In batch adsorption experiments with a fixed contact time of 120 min, experimental variables were selected as pH (2-10), metal solution concentration (2-10 mg/L), adsorbent dosage (0.03-0.07 g), and temperature (30-50 °C). These four independent variables were optimized using response surface methodology based on a four-independent variable face-centered central composite design. The optimum conditions for Copper (II) adsorption were found to be Copper (II) ion concentration of 7.3 mg/L, pH of 5.9, 0.03 g of adsorbent dosage, and temperature of 33 °C . At the optimized conditions, up to 79 % Copper (II) heavy metal ions managed to remove from heavy metal solution onto Brassica Napus straw. The face-centered central composite design proposed turned out be the best statistical model to predict the response with good accuracy and a high regression coefficient (R2=0.992). Results clearly suggest that Brassica Napus straw can be used for the Copper (II) adsorption as a low-cost adsorbent.

Özet

Bu çalışmada sulu çözeltilerden Bakır (II) giderimi için ham Brassica Napus bitki sapları adsorban olarak kullanılmıştır. Kesikli adsorpsiyon deneylerinde sabit 120 dakikalık temas süresince, pH (2-10), metal çözelti derişimi (2-10 mg/L), adsorban miktarı (0.03-0.07 g), ve sıcaklık (30-50 °C) adsorpsiyon deney değişkenleri olarak seçilmiştir. Bu dört bağımsız değişken yüzey merkezli merkezi birleşik tasarımına dayanan yüzey yanıt yöntemi kullanılarak optimize edilmiştir. Bakır (II) adsorpsiyonu için optimum koşullar 7.3 mg/L bakır (II) iyon derişimi, 5.9 pH, 0.03 g adsorban miktarı ve 33 °C olduğu yüzey merkezli merkezi birleşik tasarım yöntemi ile bulunmuştur. Elde edilen bu optimum koşullarda, adsorbanının %79 kadar Bakır (II) ağır metal giderimini gerçekleştirdiği deneysel yöntemlerle hesaplanmıştır. Önerilen yüzey merkezli merkezi birleşik tasarımının iyi bir doğruluk ve yüksek regresyon katsayına (R2=0.992) sahip en iyi istatiksel yöntem olduğu bulunmuştur. Sonuçlar açık bir biçimde Brassica Napus bitki saplarının ucuz bir adsorban olarak Bakır (II) giderimi için kullanılabileceğini göstermektedir.
