Dispers Blue 56 Boyasının Fe3O4 Gömülü Akrilamit Temelli Polimer İle Giderimi

Bu çalışmada Dispers Mavi 56 isimli boyanın Fe3O4 tanecikleri gömülü akrilamit - triazin polimeri ile giderimiaraştırılmıştır. Adsorpsiyona etki edebilecek olan, pH, etkileşim zamanı, karıştırma hızı, sıcaklık, başlangıç boyakonsantrasyonu ve adsorbent miktarı parametreleri incelenmiştir. Optimum koşullar altında, 25 mg/L başlangıç boyakonsantrasyonu ve 1.5 g polimer kullanılarak %96.6 giderim verimine ulaşılmıştır. Boya konsantrasyon ölçümleri UVVis spektrofotometresi kullanılarak yapılmıştır. Sentezlenen polimerin adsorpsiyon öncesi ve sonrası FTIRspektrumları alınmıştır. Adsorpsiyon mekanizmasını araştırmak amacıyla yalancı birinci derece modeli, yalancı ikinciderece modeli, Langmuir ve Freundlich izoterm sabitleri hesaplanmıştır. Sonuçlara göre adsorpsiyonun yalancı ikinciderece kinetik modeline ve Langmuir izotermine uyduğu görülmüştür.

Removal of disperse blue 56 dye by Fe3O4 embedded acrylamide based polymer

In this study, removal of Disperse Blue 56 dye by Fe3O4 particles embedded acrylamide – triazine polymer wasinvestigated. The possible effects of pH, interaction time, agitation speed, temperature, initial dye concentration andadsorbent dosage parameters on the adsorption were investigated. In the presence of 25 mg/L concentration of dye, theremoval efficiency was reached 96.6% by using 1.5 g of polymer under optimum conditions. Dye concentrations weremeasured by UV-Vis spectrophotometer. The FTIR spectra of synthesized polymer were taken before and afteradsorption. In order to investigate adsorption mechanism, the constants of pseudo-first-order, pseudo-second-order,Langmuir and Freundlich isotherms were calculated. According to the results, the adsorption well fitted with pseudosecond-order kinetic model and Langmuir isotherm.
