摘要
由于海水中含盐成分较高,在测定其总有机碳含量的过程中可能出现盐分沉积,影响检测结果,为此提出应用ET1020A型总有机碳分析仪检测海水中的总有机碳含量。在分析含3%盐分的水样时,测定3 d内仪器没有受到盐在催化剂上沉积的影响,稳定性很好,相对标准偏差在2%以内。当测定水样过多时,需要清除燃烧炉内的盐沉积。
Due to the high salt content in the seawater, the salt deposition may arise in the process of determination of the total organic carbon content, which could affect the test results. Considering that, ET1020A total organic carbon analyzer was used to analyze the total organic carbon in the seawater. In the analysis of a water sample containing 3% salt, the instrument was not subject to the influence of the salt deposited on the catalyst within three days. The stability of the results was good, and the relative standard deviation was within 2%. The combustion furnace needed to be cleaned after analysis of many water samples.
