SENTETİK ATIK SULARDAN BOYAR MADDELERİN KİTOSAN, ÇAPRAZ BAĞLI KİTOSAN VE KİTOSAN-POLİ (AKRİLİK ASİT) KONJUGATI İLE GİDERİLMESİ

Remazol Brillant Blue R (RBBR) ve Naphtol Blue Black (NBB) boyar maddeleri tekstil endüstrisinde yaygın olarak kullanılmaktadır. Bu çalışmada, RBBR ve NBB boyar maddeleri kitosan, çapraz bağlı kitosan ve kitosan-poli(akrilik asit) (PAA) konjugatı ile giderildi. Çapraz bağlı kitosan ve kitosan-poli(akrilik asit) konjugatı mikrodalga enerjisi kullanarak sırasıyla 15 ve 30 dakikada sentezlendi. RBBR boyar maddesi kitosan-poli(akrilik asit) konjugatı ile pH: 4.0 ve pH: 5.0’te sırasıyla % 70.23 ve % 80.78 giderildi. NBB ve RBBR çapraz bağlı kitosan ile kitosan-poli(akrilik asit) konjugatına göre daha yüksek bir yüzde ile giderildi. NBB ve RBBR boyar maddeleri kitosan ve çapraz bağlı kitosan kullanılarak yaklaşık olarak % 100 boya giderme yüzdesi ile başarılı bir şekilde giderildi.

DYESTUFFS REMOVAL FROM SYNTHETIC WASTEWATER WITH CHITOSAN, CROSS-LINKED CHITOSAN AND CHITOSAN-POLY (ACRYLIC ACID) CONJUGATE

Remazol Brillant Blue R (RBBR) and Naphthol Blue Black (NBB) dyestuffs are commonly utilized in the textile industry. In this study, RBBR and NBB dyestuffs were removed with chitosan, cross-linked chitosan and chitosan-poly(acrylic acid) (PAA) conjugate. Cross-linked chitosan and chitosan-poly(acrylic acid) conjugate were synthesized at 15 and 30 minutes respectively by using microwave energy. RBBR dyestuff was removed 70.23 % and 80.78 % at pH: 4.0 and pH: 5.0 respectively by chitosan-poly(acrylic acid) conjugate. NBB and RBBR were removed higher percent with crosslinked chitosan than chitosan-poly(acrylic acid) conjugate at acidic pHs. NBB and RBBR were removed successfully with approximately 100 % dye removal percentage using both chitosan and cross-linked chitosan.
