Hi. I am trying to adsorb Rhenium on Bacteria. I am using KReO4 salt of rhenium. After adsorption my results are very strange. Every time i did adsorption, Bacteria adsorbed Florine instead of Rhenium. Adsorbed quantity of Florine is far more than Rhenium. I also tried with some other adsorbents but the results are same. Is there any problem in my Adsorbate? I searched a lot but didn't find good solution. Kindly suggest me some ideas. Thank you
