| pH是海洋碳循环系统的重要参数之一，现有的pH标准物质是以纯水配制的缓冲溶液，以人工海水为介质的海水pH标准物质能消除液接误差，更适合于碳酸盐体系各分量的分析，因此有必要研究海水pH标准物质的批量生产方法，使其产品化、市场化。本文具体描述了海水pH标准物质生产装置的研制原理，从脱气、定量调配、分装三个环节详细描述了该生产装置的工艺流程。从中间过程控制和标准物质成品验证两方面对该生产装置进行了试验验证，验证结果表明该生产装置基本具备生产海水pH标准物质的能力，并对后续工作提出建议。 |
| 英文摘要: |
| pH is one of the important parameters of the ocean carbon cycle system. The existing pH standard material is prepared with purified water buffer solution, while the pH of seawater reference material in artificial seawater can eliminate the liquid junction error, which is more suitable to the analysis of the various components of the carbonate system. So it is necessary to study production method of the seawater pH of standard material, and make it commercially available in the market. This paper describes the research principle of seawater pH of standard material production device, and the process of the production of the device from degassing, quantitative allocation and packing. The production device is verified by test from the middle process control and standard substance completed product verification. The test results show that the seawater pH of standard material production device has a basic production ability and some suggestions are put forward for the future work. |
