Dispers mavi 56 boyasının Fe3O4 gömülü akrilamit temelli polimer ile giderimi

Bu çalışmada Dispers Mavi 56 isimli boyanın Fe3O4 tanecikleri gömülü akrilamit - triazin polimeri ile giderimi araştırılmıştır. Adsorpsiyona etki edebilecek olan, pH, etkileşim zamanı, karıştırma hızı, sıcaklık, başlangıç boya konsantrasyonu ve adsorbent miktarı parametreleri incelenmiştir. Optimum koşullar altında, 25 mg/L başlangıç boya konsantrasyonu ve 1.5 g polimer kullanılarak %96.6 giderim verimine ulaşılmıştır. Boya konsantrasyon ölçümleri UVVis spektrofotometresi kullanılarak yapılmıştır. Sentezlenen polimerin adsorpsiyon öncesi ve sonrası FTIR spektrumları alınmıştır. Adsorpsiyon mekanizmasını araştırmak amacıyla yalancı birinci derece modeli, yalancı ikinci derece modeli, Langmuir ve Freundlich izoterm sabitleri hesaplanmıştır. Sonuçlara göre adsorpsiyonun yalancı ikinci derece 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 was investigated. The possible effects of pH, interaction time, agitation speed, temperature, initial dye concentration and adsorbent dosage parameters on the adsorption were investigated. In the presence of 25 mg/L concentration of dye, the removal efficiency was reached 96.6% by using 1.5 g of polymer under optimum conditions. Dye concentrations were measured by UV-Vis spectrophotometer. The FTIR spectra of synthesized polymer were taken before and after adsorption. 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.
