以葡萄糖、丙烯酰胺为原料,过硫酸钾为引发剂,一步水热法合成了酰胺化碳微球(HTC-AM),并利用红外光谱、扫描电镜进行表征,同时研究了HTC-AM对铀的吸附性能。结果表明:温度298.15K,pH=5.0,吸附平衡时间150min时,HTC-AM达到最大的吸附能力,HTC-AM的吸附量由32.72mg/g提高到244.3mg/g,对铀的吸附符合准二级动力学模型、Langmuir吸附等温模型。说明HTC-AM可以作为高效的吸附剂用以除去水中的铀。
Amorphous carbon microspheres (HTC-AM) were synthesized by one-step hydrothermal method using glucose and acrylamide as raw materials and potassium persulfate as initiator, and characterized by IR and SEM. The effect of HTC-AM on uranium The adsorption performance. The results showed that HTC-AM reached its maximum adsorption capacity at 298.15K, pH = 5.0 and adsorption equilibrium time 150min. The adsorption capacity of HTC-AM increased from 32.72mg / g to 244.3mg / g, Second-order kinetic model, Langmuir adsorption isotherm model. Description HTC-AM can be used as a highly efficient adsorbent to remove uranium in water.
