FORMALDEHİT İLE MODİFİYE EDİLMİŞ ŞEKER PANCARI KÜSPESİ KULLANILARAK KESİKLİ SİSTEMDE SULU ÇÖZELTİDEN BAZİK KIRMIZI 46’NIN GİDERİLMESİ

Bu çalışmada, şeker pancarı küspesi (ŞPK), ilk olarak, sodyum hidroksit çözeltisi ile işleme tabi tutuldu ve ikinci olarak, birinci kademeden elde edilen saponifiye şeker pancarı küspesi, formaldehit ile modifiye edildi. Şeker pancarı küspesinden formaldehit ile modifiye edilmiş ürün (ŞPKF), sulu çözeltiden bazik kırmızı 46 (BK46)’nın giderilmesi için kullanıldı. Giderilme için etkin doz, 2 g/L olarak belirlendi. 25°C’de, 0.5 mM derişimdeki 100 mL BK46 çözeltisi, 2 g/L dozundaki ŞPKF ile kesikli kaplarda 360 dakika çalkalandı ve bu koşullar altında BK46'nın % 80.8'inin giderildiği belirlendi. Ayrıca, BK46 giderilmesi üzerine pH ve sorbent dozunun etkileri incelendi. Zamana karşı elde edilen sorpsiyon kapasitesi değerleri, yalancı birinci mertebe, yalancı ikinci mertebe, Elovich, gözenek difüzyonu, modifiye Freundlich ve Banghman kinetik modellerine uygulandı ve BR46 giderilmesini için en iyi model, yalancı ikinci derece kinetik model olarak tespit edildi. 0.10-2.50 mmol/L arası başlangıç konsantrasyonlarındaki BR46 çözeltileri, 2 g/L dozundaki sorbentler ile temas ettirildi ve çeşitli denge verileri elde edildi. Bu denge verileri, Langmuir, Freundlich, Dubinin-Radushkevich, Frumkin, Temkin ve Elovich izotermleri kullanılarak analiz edildi ve verilerin en iyi uyum sağladığı izotermlerin Langmuir ve Dubinin-Radushkevich izotermleri olduğu tespit edildi.

In this study, firstly, sugar beet bagasse (ŞPK) was treated with sodium hydroxide solution and secondly, saponified sugar beet bagasse obtained from first stage was modified with formaldehyde. The modified product from sugar beet bagasse with formaldehyde (ŞPKF) was used for removal of basic red 46 (BK46) from aqueous solution. The effective dose for removal was found to be 2 g/L. At 25 °C, 100 mL of 0.5 mM concentration solution of BK46 with 2 g/L of ŞPKF was contacted in batch containers for 360 minutes and it was determined that 80.8% of BK46 was removed under these conditions. Furthermore, the effects of pH and sorbent dose on removal of BK46 were investigated. The sorption capacities data that obtained against time were applied pseudo-first-order, pseudo-secondorder, Elovich, intra-particle diffusion, modified Freundlich ve Banghman kinetic models and the best kinetic model for BK46 removal was determined to be the pseudo second order kinetic model. The BK46 solutions that a range from 0.10 mmol/L to 2.50 mmol/L of initial concentration were contacted with 2 g/L dose of sorbent and equilibrium data were obtained. These equilibrium data were analyzed by using Langmuir, Freundlich, Dubinin-Radushkevich, Frumkin, Temkin ve Elovich isotherms and it was determined that best-fit models for data are Langmuir and Dubinin-Radushkevich isotherms
