在该项目中,开发了一种用于精确测量海水中溶解的二氧化碳(CO_2)以及空气中存在的CO_2的新装置,以分析各种溶解的二氧化碳并确定CO_2在海洋和空气之间的分配平衡。研究结果如下: 1.高效气体扩散装置的开发。发现管状微孔PTFE膜对于气态CO_2的分离非常有用,并将其安装在气体扩散装置中,无需任何胶水。 2. CO_2高灵敏检测系统的研制。采用多种酸性染料研究了灵敏检测CO_2的显色反应:发现甲酚红效果最好。此外,还合成了新型染料并进行了现场测量。在合成的试剂中,4-(2,4-二硝基苯基偶氮)-1-萘酚-5-磺酸是最好的。该系统采用新开发的试剂,用于便携式 FIA.3。开发非二氧化碳水制备系统。该系统由离子交换柱和泵组成,采用不含CO_2的纯化水,用于水中总二氧化碳的灵敏测定。 4.开发总CO_2测定系统。该系统由双柱塞泵、六路注射器、反应线圈、检测器和本研究中新开发的气体扩散装置组装而成。此外,还开发了一款一体式便携式FIA系统;该系统使用12V电池工作,数据存储在存储卡或笔记本电脑中。利用该系统可实现海洋和空气中CO_2的现场分析。 5.二氧化碳在海洋和大气之间的分配平衡研究。利用便携式FIA可以在现场快速实现平衡,并利用总浓度和平衡常数对每种溶解CO_2进行分析。较少的
英文摘要
In this project, a new apparatus for accurate measurement of carbon dioxide (CO_2) dissolved in sea water, as well as CO_2 present in air, was developed to analyze various species of dissolved carbon dioxide and to determine the distribution equilibrium of CO_2 between sea and air. The results are summarized as follows.1. Development of high-efficiency gas diffusion unit. A tubular microporous PTFE membrane was found to be very useful for the separation of gaseous CO_2, and was installed in the gas diffusion apparatus without any glue.2. Development of highly sensitive detection system for CO_2. The coloration reaction for the sensitive detection of CO_2 was investigated by using various kinds of acidic dyes : Cresol Red was found to be the best. Furthermore, new kinds of dyes were synthesized and examined for the on-site measurement. Of the reagents synthesized, 4- (2,4-dinitrophenylazo) -1-naphthol-5-sulfonic acid was the best of all. This system with the newly developed reagent was … More used for the portable FIA.3. Development of the system for the preparation of non-carbon-dioxide water. The system was assembled with ion exchange columns and a pump, and the purified water without CO_2 was used for the sensitive determination of total carbon dioxide in water.4. Development of systems for the determination of total CO_2. The system was assembled using a double-plunger pump, a six-way injector, a reaction coil, a detector and the gas-diffusion apparatus newly developed in this study. Further, a one-box portable FIA system was developed ; the system worked with a 12V battery, and the data was stored in memory cards or a note-type personal computer. By using this system, on-site analysis of CO_2 in sea and air could be achieved.5. Study on the distribution equilibrium of carbon dioxide between sea and air. The equilibrium could be achieved rapidly on site with the portable FIA,and each species of dissolved CO_2 was analyzed using the total concentration and the equilibrium constants. Less
