　　【化工仪器网政策标准】目前我国海洋石油勘探开发的不断进行，海洋石油平台也成为除江河径流和大气沉降外，向海洋输送污染的一个重要污染源。在开阔海域，钻井泥浆和钻屑对海洋环境中痕量污染元素的构成有着重要的影响，社会对其也日益关注。针对海洋石油勘探开采产生大量钻屑泥浆等污染物排放入海问题，国外已经制定了相关先进的含油污染物的沉积物微波辅助酸消解前处理方法和ICP-MS分析方法，而我国暂时还没有出台相关国家或行业标准。故而制订相关标准法规势在必行。

　　近日，由国家海洋局南海环境监测中心起草的《海洋石油钻井泥浆和钻屑中重金属的测定微波消解-电感耦合等离子体质谱法》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10日。

　　阅读标准征求意见稿后可知，《海洋石油钻井泥浆和钻屑中重金属的测定微波消解-电感耦合等离子体质谱法》是按照GB/T 1.1-2016给出的规则起草的，内容主要包括有范围、术语和定义、方法原理、试剂，材料及制备、仪器及设备、分析步骤、记录与计算、精密度和准确度、试验报告、注意事项以及资料性附录。

　　标准规定了用微波消解-电感耦合等离子体质谱法测定海洋石油勘探开发钻井泥浆和钻屑样品中铜、铅、锌、镉、铬。其方法原理是钻屑泥浆经预处理后，利用硝酸-双氧水消解，在稀硝酸介质中，利用氩气作为载气将样品送入雾化器形成气溶胶，在等离子体中原子化，经四级杆碰撞/反应池消除干扰离子，根据检测器产生的信号值和对应元素的灵敏度因子K值，即可计算样品中该元素的含量。而实验需要用到的仪器设备有：具备碰撞/反应池的电感耦合等离子体质谱仪、电子天平以及高控温设置大于等于300℃，温度误差小于±2℃的微波消解仪。

　　本方法标准充分考虑了目前国内通用的不同型号的电感耦合等离子体质谱仪和微波消解仪的工作原理及特点，同时兼顾了相关仪器使用的环境、检测条件。相信随着本标准的正式实施，能有效提高海洋石油勘探开发钻井泥浆和钻屑中重金属分析的前处理效率，提高钻屑泥浆重金属分析数据的可比性，降低人员健康暴露，并为海洋环境管理提供科学支持，同时促进海洋标准化的发展。
