Helianthus Annuus Çekirdeği Kabuklarında Uranyum Sorpsiyonu

Biyosorpsiyon, biyokütlede doğal olarak gerçekleşen, biyokütlenin pasif olarak konsantre etme ve kirlilikleri hücresel yapısı üzerine bağlamasını sağlayan fizikokimyasal bir işlemdir. Sulu çözeltilerden Helianthus Annuus çekirdeği kabuklarında uranyum biosorpsiyonu batch adsorpsiyon sistemiyle, pH, adsorbat konsantrasyonu ve sıcaklığın bir fonksiyonu olarak "Box-Behnken Design" modeli kullanılarak incelenmiştir. Öncelikle adsorpsiyon süresinin belirlenmesi amacıyla denemeler yapılmış ve 2 saatlik çalkalama süresi optimum süre olarak bulunmuştur. Sonuç olarak başlangıç uranyum konsantrasyonu 127,5 ppm; pH 4,5 ve 20°C sıcaklık optimum koşullar olarak saptanmıştır.

Uranium Sorption on Helianthus Annuus Core Shell

Biosorption is a physicochemical process that occured naturally in biomass, passive concentration and bind the contaminants in its cellular structure. The biosorption of uranium from aqueous solution by Helianthus Annuus core shell was studied in a batch system as a function of initial pH, initial concentration of adsorbate and temperature by using "Box-Behnken Design" method. Firstly, for determining the adsorption time, effect of contact time was investigated and 2 hours shaking time was chosen as an optimum period. Consequently, optimum conditions were determined as initial concentration of 127.5 ppm, pH 4.5 and temperature of 20°C.
