Abstract

Activated coal produced from Ağaçlı Lignite coal was used to remove Cr(VI) from aqueous solutions. The adsorption of Cr(VI) was studied as a function of initial concentration, time, pH, adsorbent concentration and temperature. The adsorption data were found to fit to Langmuir and Freundlich isotherms. Lagergren equation was used to calculate the adsorption rate. The amount of Cr(VI) adsorbed was increased with decreasing pH and decreased with increasing temperature.

Özet

Ağaçlı Linyit kömürlerinden elde edilen aktif kömür, sulu çözeltilerden Cr(VI) uzaklaştırmak için kullanılmıştır. Cr(VI) adsorpsiyonu başlangıç konsantrasyonu, zaman, pH, adsorbent konsantrasyonu ve sıcaklığın fonksiyonu olarak çalışılmıştır. Adsorpsiyon verileri Langmuir ve Freundlich izotermlerine uydurulmuştur. Adsorpsiyon hız sabitini hesaplamak için Lagergren eşitliği kullanıldı. Adsorbe edilen Cr(VI) miktarı pH değerinin azalması ile artmış, sıcaklığın artması ile azalmıştır.
