目前,我国国家标准采用气量法测定二氧化碳,其装置是由复杂的成套玻璃器皿组成,对不具备条件的单位无法测定。现将笔者所使用的简易方法介绍如下。1 方法原理将试样用盐酸分解,释放出的二氧化碳用氢氧化钠吸收,在吸收液中加入氯化钡溶液,将生成的碳酸钡沉淀过滤并洗涤,再
At present, China’s national standard for the determination of carbon dioxide gas method, the device is composed of a complex set of glassware, can not be determined for the unit does not have the conditions. Now I use the simple method described below. Principle 1 Method The sample was decomposed with hydrochloric acid, the release of carbon dioxide with sodium hydroxide absorption, barium chloride solution was added to the absorption solution, the resulting barium carbonate precipitate was filtered and washed, and then
