Sulu Çözeltilerden Fosfor Gideriminde Demir ile Kaplanmış Aktif Karbonun Kullanılabilirliğinin Araştırılması

Fosfor canlılar için temel bir nütrient olmasının yanı sıra sucul ortamlarda çok düşük konsantrasyonlarda ötröfikasyon adı verilen çevresel bir probleme sebep olmaktadır. Bu araştırmada ticari olarak satışı olan aktif karbon malzemesi demir ile kaplanarak sentezlenen yeni malzeme (DKK) ile fosfor giderimi araştırılmıştır. Yapılan laboratuvar çalışmaları sonucunda DKK’nın sulu çözeltilerde fosfor gideriminde işlevsel olarak kullanılabileceği anlaşılmıştır. Ayrıca malzemenin fosfor tutma kapasitesinin 4,26 mg PO43-/g DKK olduğu tespit edilmiştir. Adsorpsiyonun Langmuir matematiksel modeline uyduğu ve üretim için uygun şartların sağlanması ile birlikte ticari olarak üretiminin gerçekleştirilerek fosfor gideriminde yaygın olarak kullanılabileceği sonucuna varılmıştır.

Investigation of Usability of Iron Coated Activated Carbon for Phosphorus Removal from Aqueous Solutions

Phosphorus is a basis nutrient for living organisms, but also causes an environmental problem called eutrophication at very low concentrations in aquatic environments. In this research, the commercially available activated carbon material was coating with iron and phosphorus removal was investigated with synthesized new material (DKK). As a result of laboratory studies, it was found that DKK can be used functionally in phosphorus removal in aqueous solutions. In addition, the phosphorus holding capacity of the material was found to be 4.26 mg PO43-/g DKK. It has been concluded that adsorption complies with the Langmuir mathematical model and can be used in phosphorus removal by commercially synthesizing with appropriate conditions for production.
