　　【化工仪器网政策标准】富勒烯具有独特的光、电和磁学特性，在生物医药、新材料和新能源等领域具有重大应用前景，其中，含有60个碳原子的[60]富勒烯和含有70个碳原子的[70]富勒烯是目前产量较高且应用广泛的富勒烯材料。化妆品和生物医药行业对[60]和[70]富勒烯有着巨大的需求，而其纯度会影响应用性能，但由于缺乏统一、规范的富勒烯纯度检测标准，目前市场上富勒烯原料鱼目混珠、纯度品质良莠不齐，阻碍了富勒烯的产业化发展。

　　为了规范和推进富勒烯相关产业化的高速发展，中国科学院化学研究所、北京福纳康生物技术有限公司起草了《[60]和[70]富勒烯的纯度测定高效液相色谱法》。该标准已经编制完成，目前正面向社会征求意见，意见征集时间截止至2021年1月22日。

　　阅读《[60]和[70]富勒烯的纯度测定高效液相色谱法》征求意见稿后可知，本标准的内容包括有范围、规范性引用文件、术语和定义、原理、试剂和材料、仪器、色谱操作条件、样品制备、测定、数据处理、精密度、测试报告以及资料性附录、规范性资料附录。

　　本标准适用于[60]和[70]富勒烯材料及用于生物医药的富勒烯复合材料中富勒烯纯度的测定，其他富勒烯及富勒烯衍生物的纯度测定可参考本文件执行。高效液相色谱法的测定原理如下：在特定条件下，利用高效液相色谱柱对溶液中[60]富勒烯或[70]富勒烯与杂质相互作用差异而使其在色谱柱上的保留时间不同，通过紫外吸收检测器检测得到不同保留时间的色谱峰，结合参考样品确定富勒烯的色谱峰与杂质的色谱峰，之后通过峰面积归一化法即可计算样品中[60]和[70]富勒烯的纯度。

　　需要注意的是，实验中需要用到的仪器设备为：实际分度值为0.01mg的分析天平、配置紫外检测器和柱温箱的高效液相色谱仪以及以5μm 球形多孔硅胶为基质，表面键合芘基丙基的色谱柱。

　　本标准的制订，是起草组收集了大量国内外相关资料，查询了国内外相关法律法规和标准方法，优化了高效液相色谱法测定富勒烯纯度的工作条件参数。相信随着标准的正式实施，将满足众多富勒烯研究、生产与应用的迫切需求，故而希望相关单位能在仔细研核后，提出建设性意见，以促进标准的可行性、适用性和科学性更上一层楼。
