MAGNETIC NANO-BIOSORPTION OF HEAVY METAL FROM AQUEOUS SOLUTIONS USING SUGARCANE BAGASSE %K Sugarcane bagasse %K Uranium %K nano biosorbent %K biosorbtion %R 10.22099/ijstc.2014.1850 %X Uranium in the environment is hazardous to human health and requires better methodsfor detection and remediation. Bioadsorbent coated on nanocrystalline iron oxides offers a numberof advantages as sorbents for water purification and environmental remediation. In this study, firsthighly uniform and crystalline iron oxide nanocrystals (nMAG) were prepared using iron salts inpresence of NaOH by co- precipitation process and then sugarcane bagasse coated on synthesizediron oxide nanocrystals has been used as a bioadsorbent for uranium solution with lowconcentration. The effect of different parameters on optimum function of this process has beenanalyzed. The results showed that maximum uranium absorption occurs at pH levels of about 3.Optimum amounts of biomass, uranium concentration and contact time are 0.1 gr, 50 ppm and 120min, respectively. Thus, the uranium biosorption by magnetic biosorbent can be considered apotential technology of treatment process for uranium removal in which the adsorbents and theadsorbed pollutant can be quickly recycled by simply applying a magnet. %U https://ijstc.shirazu.ac.ir/article_1850_e46949749e61d4b20b23207396a82566.pdf
