Biochar most effective in removing radioactive cesium

Removal of Radioactive Cesium (Cs-134 plus Cs-137) from Low-Level Contaminated Water by Charcoal and Broiler Litter Biochar

Kimura et al., Mar 09, 2015

Various charcoals (used in food processing and water treatment) and broiler litter biochar were examined for
ability to adsorb water-soluble low-level radioactive cesium (ca. 200_250 Bq/kg) extracted from contaminated wheat bran. Among the materials tested, steam activated broiler litter biochar was the most effective sorbent and was able to reduce the concentration of radioactive cesium to less than 10 Bq/kg.
