ORGANİK ATIKLARDAN ÜRETİLEN KOMPOZİT BİR MODİFİYE BİYOKÖMÜR KULLANILARAK SULU ÇÖZELTİDEN SAFRANİN T GİDERİMİ

Modern yaşamın ilgi çekici unsurlarından biri de renktir. Başta tekstil endüstrileri olmak üzere bir çok endüstri, farklı konsantrasyonlarda çeşitli boyalar içeren yüksek miktarda renkli atık su üretmektedir. Sağlık ve ekolojik kaygılara yol açan sentetik boyaların alıcı ortama verilmeden önce atıksulardan uzaklaştırılması gerekmektedir. Düşük maliyetli adsorbanlar elde edebilmek için atık malzemelerin kullanımı, atıksu arıtma maliyetlerinin azaltılmasına ve çevrenin korunmasına katkıda bulunduğu için araştırmalara konu olmaktadır. Bu çalışmada, kolayca temin edilebilen ve toksik olmayan organik üretilen aktive edilmiş kompozit bir biyokömür hazırlanarak Safranin T boyasının gideriminde adsorbent olarak kullanılmıştır. Kesikli sistemde gerçekleştirilen deneylerde adsorban miktarı (0,1-1 g/L), boya konsantrasyonu (10-50 mg/L), pH (5-9) ve temas süresi (0-360 dk) gibi en temel parametreler incelenmiştir. Dört farklı İzoterm ve dört farklı kinetik tartışılmıştır. Elde edilen verilerle Langmuir izoterm modeli ve sözde ikinci derece kinetik model daha iyi uyum sağlamıştır.
