Polianilin/Aljinat Kompozit Malzemesinin Asit Violet 90 Boyar Maddesinin Gideriminde Kullanılması: Kinetik Ve İzoterm Değerlendirmesi
Öz
Bu çalışmada Polianilin/Aljinat (PANİ/SA) kompozit malzemesi Asit Violet 90 (AV 90) boyar maddesinin adsorpsiyonunda kullanılmıştır. PANİ/SA’nın karakterizasyonu Fourier Dönüşüm Kızılötesi Spektroskopisi (FTIR ile analiz edilmiştir. pH (2-6), PANİ/SA küre miktarı (10-50 adet) ve AV 90 derişiminin (25-200 mg/L) boyar madde giderimine etkisi incelenmiştir. En yüksek boyar madde giderimi pH 2’de elde edilmiştir. AV 90 adsorpsiyon izotermlerini belirlemek için Langmuir, Freundlich ve Temkim izoterm modelleri kullanılmıştır. 25-200 mg/L boyar madde derişimi aralığında Langmuir modelinden elde edilen maksimum adsorpsiyon kapasitesi (qm) değeri 138,9 mg/g olarak bulunmuştur. Adsorpsiyon kinetiğinin belirlenmesi için yalancı birinci derece ve ikinci derece kinetik modelleri kullanılmış ve en Yalancı ikinci derece kinetik modelin deney verileri ile daha uyumlu olduğu görülmüştür. Deney sonuçları PANİ/SA adsorbentinin AV 90 boyar maddesinin adsorpsiyonu için oldukça iyi bir alternatif olduğunu göstermiştir.
