Abstract

This paper presents the adsorption characteristics for the removal of Cr (VI) from aqueous solutions using alumina obtained from Etibank Aluminum Plant. In order to define the optimum conditions, the effects of contact time, activation process, pH of solution, initial concentration, adsorbent dose and salinity on the removal of Cr (VI) have been investigated. It is shown that the Freundlich Isotherm Model adequately described batch adsorption data. Although the removal percentage of Cr(VI) on activated alumina under optimal conditions is high, in practice, it could not be used as a potential sorbent for removal of Cr(VI) because high dose of adsorbent.

Özet

Bu makale, Etibank Alüminyum Fabrikasından temin edilen alumina ile sulu çözeltilerden Cr(VI) giderimi için adsorpsiyon karakteristiklerini sunmaktadır. Optimum şartları tayin etmek amacıyla, temas süresinin, aktivasyon prosesinin, çözelti pH'nın başlangıç konsantrasyonunun, adsorbent dozajının ve tuzluluğun Cr(VI) giderimindeki etkisi incelenmiştir. Freundlich İzoterm Modelinin adsorpsiyon verilerini oldukça iyi tanımladığı görülmüştür. Optimum şartlarda Cr(VI)'nın aktif alumina üzerindeki giderim yüzdesi yüksek olmasına rağmen, yüksek adsorbent dozajı gerektirdiğinden uygulamada Cr(VI) giderimi için potansiyel bir sorbent olarak kullanılamaz.
