Bu çalışmada, katyonik bir boya olan Bazik Mavi 3'ün, kitosan bazlı boncuk formdaki polimerik sorbentler kullanılarak sulu ortamdan uzaklaştırılması amaçlanmıştır. Ki-tosan bazlı polimerik boncukları oluşturmak için çökelt-me-toplama yönteminden faydalanılmıştır. Daha sonra, kitosan bazlı sorbentin sorpsiyon aktivitesi katyonik boyar madde (Bazik Mavi 3, BB3) içeren atık su kullanılarak değerlendirilmiştir. Boya moleküllerinin sorpsiyon etkinliği üzerinde, sıcaklık, başlangıç pH'ı, sorbent dozajı, başlangıç boya çözeltisi kon-santrasyonu, temas süresi vb. gibi farklı sorp-siyon parametrelerinin etkisi incelenmiştir. Optimum çözelti sıcaklığı, başlangıç pH'ı, kitosan konsantrasyonu, temas süresi ve BB3 boyasının başlangıç konsantrasyonu sırasıyla 298 K, 10,5 ± 0,02, 240 dakika, 1 g/L ve 150 mg/L olarak tespit edildi. Bu şartlarda sorbentin optimum sorpsiyon kapasitesi 59.89 mg/g olarak bulundu. Kitosan boncuklarının fiziksel kararlılıklarını koruduğu görüldü.

Sorption of Basic Blue 3 Dye Molecules from Aqueous Solution with Chi-tosan-Based Beads without Crosslinkers

Öz

In this study, it was aimed to remove Basic Blue 3, a cationic dye, from aqueous media by using chitosan based polymeric sorbents in bead form. The precipi-ta-tion-measurement method was used to form chitosan based polymeric beads. Then, the sorption activity of chitosan based sorbent was evaluated using was-tewater con-taining cationic dye (Basic Blue 3, BB3). The effects of different sorption parameters such as temperature, initial pH, sorbent dosage, initial dye solution concentration, contact time etc. on the sorption efficiency of dye mole-cules were investigated. The optimum solution temperature, initial pH, chitosan concentration, contact time and initial concentration of BB3 dye were determined as 298 K, 10.5 ± 0.02, 240 min, 1 g/L and 150 mg/L, respectively. The optimum sorption capacity of the sorbent under these conditions was found to be 59.89 mg/g. Chitosan beads were found to maintain their physical stability.
