Bu çalışmada, Boletus edulis biyokütlesi ile sulu çözeltilerden Direct Blue 2 boyar maddesinin giderimi çalışılmıştır. Bu amaçla biyosorbent olarak hazırlanan B. edulis biyokütlesi ile farklı koşullarda DB2 giderim çalışmaları gerçekleştirilmiştir. Biyosorbent miktarı, başlangıç DB2 derişimi, pH, biyosorpsiyon sıcaklığı ve sürenin optimizasyonunun ardından izoterm, kinetik ve termodinamik parametreler hesaplanmıştır. Elde edilen verilere göre, 0,02 g/0,02 L biyosorbent miktarının kullanıldığı koşullarda biyosorpsiyon kapasitesi pH:3,0’te 25 ⁰C’de 200 mg/L başlangıç DB2 derişimi için 136,149±0,801 mg/g bulunmuştur. Biyosorpsiyon prosesinin yalancı ikinci derece kinetik modele ve Freundlich izoterm modeline uyumlu, biyosorpsiyonun ekzotermik karakterde olduğu bulunmuştur.
In this study, the removal of Direct Blue 2 dyestuff from aqueous solutions by Boletus edulis biomass was investigated. For this purpose, DB2 removal was investigated under different conditions with B. edulis biomass prepared as biosorbent. After optimization of biosorbent amount, initial DB2 concentration, pH, temperature and time, isotherm, kinetics and thermodynamics were calculated. According to the obtained data, the biosorption capacity was found to be 136.149±0,801 mg/g for 200 mg/L initial DB2 concentration at 25 ⁰C at pH: 3.0 under conditions where 0.02 g biosorbent amount was used. The biosorption process was fitted with the pseudo-second order kinetic model and Freundlich isotherm model, and the biosorption was found to be exothermic.
