测定水中二氧化碳有中和滴定、微量扩散和气相色谱法。其气相色谱法系用载气将水中二氧化碳气化后通过分离柱进行色谱测定。作者提出了在容器中至气液平衡后注入气相色谱定量的简便方法。用已校正好的100ml注射器,通过碱石灰管除去二氧化碳,抽取无二氧化碳的空气50ml,然后再吸取水样50ml,套上橡皮帽,将注射器浸入恒温水浴中5分钟,取出振摇30
Determination of water with carbon dioxide titration, trace diffusion and gas chromatography. The gas chromatography with a carrier gas carbon dioxide gasification after the separation column chromatography. The authors propose a simple and convenient method of quantifying gas by gas injection in a container after gas-liquid equilibrium. Using a calibrated 100ml syringe, remove the carbon dioxide through a soda lime tube, extract 50ml of air without carbon dioxide, and then draw 50ml water sample, put on a rubber cap, the syringe immersed in a constant temperature water bath for 5 minutes, shake out 30
