Abstract
Sediment, nehirlerin, göllerin, koyların, haliçlerin ve okyanusların tabanında yer alan yeryüzü katmanıdır. Dünyanın en büyük soda gölü olması, eşine rastlanmayacak büyüklükte ve güzellikte dipten yükselen güncel karbonat sütunları içermesi ve su seviyesinde yaşanan değişimler, Van Gölü’nü dünyanın en ilginç göllerinden biri yapar. Bu çalışmada Van Gölünden alınan doğal sediment ve asitle (HNO3) aktive edilmiş sedimentlerin ağır metal (Cr3+) ile ilişkisi batch adsorpsiyon tekniği kullanılarak saptanmaya çalışılmıştır. Farklı konsantrasyonlardaki krom (Cr3+) iyonlarının ve pH’ın adsoprsiyon prosesi üzerine etkisi araştırılmıştır. Langmuir, Freundlich, Dubinin-Radushkevich (D-R) ve Temkin adsorpsiyon izotermleri hesaplanmıştır. Hem doğal sediment (DS) hem de asitle modifiye edilmiş sedimentin (MS) Langmuir adsorpsiyon izoterm modeline uyum sağladığı bulunmuştur. Bununla birlikte hem doğal adsorbent hem de asitle modifiye edilmiş adsorbentin termodinamik parametreleri hesaplanmış, ΔG° < 0 değerinin adsoprsiyon prosesinin kendiliğinden gerçekleştiğini göstermiştir. Doğal sedimentin yüzey alanı 7.512 m²/g, asit ile aktive edilmiş sedimentin yüzey alanı 79.456 m²/g tespit edilmiş olup aktivasyon işlemi ile çok yüksek bir yüzey alanı elde edilmiştir. Giles adsorpsiyon izoterm sistemine göre H tipi eğriye uyduğu görülmüştür.
