Abstract

In this study, determination of biosorption removal isotherm coefficients by Matlab programme for copper ions from aqueous solution has been studied. Biosorption by immobilized dead Rhizopus arrhizus was examined in this study. The most appropriate isotherm coefficient values was determined by evaluating non-linear and linear forms of Langmuir, Freundlich and BET isotherm models with experimental data. When the models were compared, Langmuir, Freundlich and BET isotherm model equilibriums' correlation coefficients of non-linear and linear forms were calculated accordingly; 0.98 and 0.92; 0.94 and 0.97; 0.78 and 0.92. Calculated average correlation coefficient values from linear and non-linear forms of Langmuir, Freundlich and BET models were 0.95, 0.96 and 0.86 respectively. As a result of comparing these correlation coefficients, usage of Freundlich and Langmuir model are more appropriate as isotherm models of copper biosorption on immobilized dead R. arrhizus.

Özet

Bu çalışmada, bakır iyonlarının $(Cu^{+2})$ sıvı ortamdan biyosorpsiyonla giderilmesinin izoterm sabitleri Matlab programı ile belirlenmiştir. Bu çalışmada tutuklanmış Rhizopus arrhizus ile biyosorpsiyon incelenmiştir. Langmuir, Freundlich ve BET izoterm modellerinin eğrisel ve doğrusal formları, deneysel veriler ile değerlendirilerek en uygun izoterm katsayı değerleri belirlenmiştir. Modeller karşılaştırıldığında; Langmuir, Freundlich ve BET izoterm denklemlerinin eğrisel ve doğrusal formlarının korelasyon katsayıları sırasıyla; 0,98 ve 0,92; 0,94 ve 0,97; 0,78 ve 0,92 olarak hesaplanmaktadır. Langmuir, Freundlich ve BET modellerinin eğrisel ve doğrusal formlarında hesaplanan ortalama korelasyon katsayıları $(R^2)$ sırasıyla; 0,95, 0,96 ve 0,86 dır. Elde edilen korelasyon katsayılarının karşılaştırılması sonucunda, bakırın tutulmuş ölü R. arrhizus üzerine biyosorpsiyonunun izoterm modeli olarak Freundlich ve Langmuir modelinin kullanılması daha uygundur.
