Abstract Removal of 137Cs radionuclides from the environment has engrossed the concern of researchers after Fukushima accident. The leakage of radioactive cesium ions can lead up to surface and groundwater contamination, and this leads to pollution of drinking water sources. In this work, corchorus olitorius stalks has been used as a novel precursor for production of low-cost meso porous a ctivated c arbon ( Meso-AC ) and HNO3/H2O2- m odified Meso-AC ( m-Meso-AC ). The physicochemical properties of all adsorbents were evaluated. The influences of sorption parameters and presence of some ligands (humic acid, fulvic acid, and EDTA) on the sorption of 137Cs were studied. The maximum 137Cs capacity of m-Meso-AC was found to be 58.74 mg/g. Efficiency of the new adsorbent to remove 137Cs radionuclides from natural waters (tap, river, and groundwater) was investigated. The studies showed that new adsorbent could be used as promising material for the retention of 137Cs from real radioactive waste and natural water samples.

吸附参数对使用从黄麻茎中获得的改性活性炭去除铯 137 的影响

摘要 福岛核事故后，环境中137Cs放射性核素的去除引起了研究人员的关注。放射性铯离子的泄漏会导致地表水和地下水污染，从而导致饮用水源的污染。在这项工作中，黄麻茎已被用作生产低成本介孔活性炭 (Meso-AC) 和 HNO3/H2O2-改性的 Meso-AC (m-Meso-AC) 的新型前体。评估了所有吸附剂的理化性质。研究了吸附参数和一些配体（腐殖酸、富里酸和 EDTA）的存在对 137Cs 吸附的影响。发现 m-Meso-AC 的最大 137Cs 容量为 58.74 mg/g。新型吸附剂从天然水体（自来水、河流、和地下水）进行了调查。研究表明，新的吸附剂可用作保留真实放射性废物和天然水样中的 137C 的有前途的材料。
