水中总有机碳的检测的影响因素

文章从储存时间、空气、光线和加酸量4各方面来探讨其对水中总有机碳检测时的影响。实验表明:储存时间对其TOC有影响,建议尽量使用新鲜的蒸馏水。空气、光线对TOC的影响呈正相关,如不加保存剂应在24 h内检测,加保存剂宜采用棕色瓶保存,7d内检测。样品加酸量对TOC结果有影响,特别是对污水影响较大,建议样品加硫酸量为1.5%。

Factors Influencing the Determination of Total Organic Carbon in Water

The article from the storage time, air, light and acid 4 aspects to explore the impact of total organic carbon in water when detecting. Experimental results show： tile storage time had influence on its TOC, suggest to use fresh distilled water. Air, light effects on the TOC were positively correlated, without preservative should be detected within 24 h, and save the agent should adopt the brown bottle storage, 7 d detection. The sample amount has influence on the result of TOC, especially the influence of sewage; suggest sample and sulfuric acid amount was 1.5 %.
