Abstract

Optimization of medium conditions for Cd II adsorption by pumice was studied through experimental designs. A multi step response surface methodology RSM including 26-2 fractional factorial design FFD , steepest ascent and central composite design CCD was successfully applied to optimize the adsorption conditions for Cd II ions from aqueous solutions. The most influential medium parameters were determined as pH, initial Cd II concentration and temperature via FFD. Then steepest ascent was used to determine the neighborhood region of the optimum point. Finally, CCD was applied to develop a response surface for optimization of adsorption conditions. The optimum conditions for Cd II adsorption were evaluated to be 7.01, 107.14 mg/L and 32.48°C for pH, initial Cd II concentration and temperature, respectively. A quadratic model was developed by CCD to represent Cd II ions adsorption.

Özet

P onza ile Cd II adsorpsiyonu için ortam koşullarının optimizasyonu deneysel tasarım ile çalışılmıştır. 26-2 Fraksiyonel faktoriyel tasarım FFD , en yüksek artış ve merkezi kompozit tasarımı MKT içeren çok basamaklı bir cevap yüzey yöntemi CYY , sulu çözeltilerden Cd II iyonlarının adsorpsiyon koşullarını optimize etmek için başarılı bir şekilde uygulanmıştır. En etkili ortam parametreleri FFD ile pH, başlangıç Cd II derişimi ve sıcaklık olarak belirlenmiştir. Daha sonra optimum noktaya yakın aralıkların belirlenmesi için en dik artış yöntemi uygulanmıştır. Son olarak, adsorpsiyon koşullarının optimizasyonunda bir cevap yüzeyi geliştirmek için MKT uygulanmıştır. Cd II adsorpsiyonu için optimum koşullar pH, başlangıç Cd II derişimi ve sıcaklık için sırasıyla 7.01, 107.14 mg/L ve 32.48°C olarak belirlenmiştir. Cd II iyonlarının adsorpsiyonunu açıklamak için MKT ile bir kuadratik model geliştirilmiştir.
