【摘要】 开展了清洗方式对低碳铀切屑样品中碳量测定的影响研究,重点探讨了蒸馏水、有机试剂、硝酸溶液对低碳铀切屑样品的清洗效果。结果表明:采用蒸馏水-硝酸溶液(体积比1∶1)加热煮沸浸洗-丙酮-乙醚处理,对低碳铀切屑样品表面的碳沾污清除效果好。更多还原

【Abstract】 The influence of methods for cleaning low carbon uranium scraps sample on the determination of their carbon contents was studied with emphasis on the effect of cleaning solvents,including distilled water,some organic reagents,and nitric acid.The experimental results show that better cleaning results can be achieved by sequential treatment of low carbon uranium scraps sample with distilled water,hot nitric acid(volume ratio 1∶1),acetone,and ethyl ether.Different cleaning consequences were observed with various cleaning methods,and possible reasons were discussed.更多还原
