Abstract

The biosorption of heavy metals, radionuclides, uranium and thorium for the recovery or removal from aqueous systems using various micro-organisms and biological substances has been investigated by several groups of workers. In this paper, the uptake of uranium (VI) from aqueous systems by a marine sponge, Sarcotragus foetidus (Schmidt, 1862) has been investigated. S. foetidus samples were collected from Babakale/Ayvacık/Canakkale in Turkey. Uranium (VI) uptake experiments were carried out by the batch technique. The affecting parameters were analyzed using Central Composite Design (CCD) as the experimental method. Four independent variables such - pH, temperature, contact time, and initial uranium concentration were selected for this study. The influences of initial pH, contact time, and initial uranium concentration on the biosorption process were considered statistically significant as main effects. On the other hand, interaction effects of pH and contact time, as well as pH and initial uranium concentration, were considered as significant parameters on the biosorption process. The optimum condition of biosorption process was found to be at init”ial pH: 4, temperature: 35°C, initial uranium concentration: 20 mg/L, and contact time: 31 minutes. At these conditions, the biosorption yield of uranium (VI) ions was obtained to be 93.29±2%

Özet

Mikroorganizmalar ve biyolojik materyaller kullanarak radyonüklitlerin, ağır metallerin, toryum ve uranyum gibi radyoaktif metallerin sulu çözeltilerden geri alınması veya uzaklaştırılması üzerine birçok çalışma vardır. Bu çalışmada, Sarcotragus foetidus (Schmidt, 1862) olarak adlandırılan deniz süngerinin sulu çözeltilerden uranyum alımı istatistiksel olarak araştırıldı. S. foetidus (Schmidt, 1862) deniz süngeri örnekleri Babakale (Ayvacık / Çanakkale) açıklarından toplandı. Uranyum (VI) geri alım denemeleri kesikli yöntem ile gerçekleştirildi. Biyosorpsiyonu etkileyen parametreler Merkezi Kompozit Deneysel Tasarımı (CCD) kullanılarak analiz edildi. Bu çalışma için; pH, sıcaklık, temas süresi ve uranyum başlangıç konsantrasyonu gibi dört bağımsız değişken seçildi. Ana parametrelerden pH, temas süresi ve uranyum başlangıç konsantrasyonu biyosorpsiyon prosesinde istatistiksel olarak anlamlı olarak kabul edildi. Diğer bir yandan; biyosorpsiyon işlemi üzerinde, pH- temas süresi, pH - uranyum başlangıç konsantrasyonu gibi ikili etkileşimler önemli parametreler olarak belirlendi. Biyosorbsiyon prosesinin optimum koşulları; pH:4, sıcaklık: 38 , uranyum başlangıç konsantrasyonu: 20 mg/L ve temas süresi: 31 dakika olarak hesaplandı. Bu koşullar altında biyosorpsiyon verimi % 93.29±2 olarak elde edildi
