Abstract

Continuously growing industrial areas cause environmental and water pollution. One of the causes of water pollutants is the dyestuffs released into the environment without being recovered. In this study, biochar and nanomagnetic biochar were obtained from silverberry seeds, and the obtained biochars were used to remove methyl blue, an anionic dye, from the aqueous medium. The effects of pH, initial methyl blue concentration, temperature, amount of adsorbent and time change on the adsorption process were investigated. The maximum adsorption capacity was found to be 55.249 mg/g for biochar (b-EA) and 66.225 mg/g for nanomagnetic biochar (mb-EA). When the adsorption isotherms were examined, it was seen that both adsorbents were more suitable for Langmuir adsorption isotherm (R2=0.963 for b-EA, R2=0.991 for mb-EA). According to the kinetic data, the adsorption rate for both adsorbents is pseudo-second-order. In addition, negative ΔG values indicate that the adsorption process occurs spontaneously and positive ΔH values endothermically.

Özet

Sürekli büyüyen endüstri alanları çevre ve su kirliliğine sebep olmaktadır. Su kirleticilerin sebeplerinden biri de geri kazanılmadan çevreye bırakılan boyar maddelerdir. Bu çalışmada iğde çekirdeklerinden biyokömür ve nanomanyetik biyokömür elde edilmiş, elde edilen biyokömürler anyonik bir boya olan metil mavisini sulu ortamdan uzaklaştırmak için kullanılmıştır. pH, başlangıç metil mavisi konsantrasyonu, sıcaklık, adsorban madde miktarı ve zaman değişiminin adsorpsiyon sürecine etkileri incelenmiştir. Maksimum adsorpsiyon kapasitesi biyokömür (b-EA) için 55.249 mg/g ve nanomanyetik biyokömür (mb-EA ) için 66.225 mg/g bulunmuştur. Adsorpsiyon izotermleri incelendiğinde her iki adsorbanında Langmuir adsorpsiyon izotermine (b-EA için R2=0.963, mb-EA için R2=0.991) daha uygun olduğu görülmüştür. Kinetik verilere göre her iki adsorban için adsorpsiyon hızı yalancı ikinci derecedendir. Ayrıca negatif ΔG değerleri adsorpsiyon sürecinin kendiliğinden, pozitif ΔH değerleri ise endotermik olarak gerçekleştiğini göstermektedir.
