Ammonia in access to some of the carbon dioxide, made of carbonated ammonia, the formation of ammonium bicarbonate.
Ammonia stored in the open air at room temperature, two days after the loss of ammonia up to 90%. In order to reduce losses, generally made of ammonium bicarbonate, can effectively reduce the loss of ammonia. Ammonium bicarbonate ammonium bicarbonate for short, also known as ammonium bicarbonate. It is made of ammonia absorption of carbon dioxide, the product is white fine crystal, about 17% nitrogen, a strong ammonia odor. Its aqueous solution is alkaline, pH is about 8 (as long as not too thin, the concentration of the pH value is not significant). At about 20 ℃, ammonium bicarbonate is basically stable, the temperature increases, when the humidity is easy to break down.
Carbonization of mother liquor or ammonia in the determination of CO2 and total ammonia, the current fertilizer plants have adopted the amount of gas and acid-base titration were quantified.
Tengzhou Xiangying Analytical Technology Co., Ltd. developed a special anti-corrosion gas chromatograph, with high peak quantitative. The method is accurate and reliable. It is simple and rapid and can be used as the control analysis of the factory.
在 氨水中通入一些二氧化碳，制成碳化氨水，形成碳酸氢铵。
氨水在常温下存放在露天，两天后氨的损失可达90%。为了减少损失，一般制成碳酸氢铵，可有效减少氨损失。碳酸氢铵碳酸氢铵简称 碳铵，也叫重碳酸铵。它由氨水吸收二氧化碳制成，产品是白色细粒结晶，含氮17%左右，有强烈氨臭味。它的水溶液呈碱性，pH值约为8（只要不是太稀，浓度对pH值的影响不大）。在20℃左右，碳酸氢铵基本上是稳定的，温度升高、湿度大时容易分解。
碳化母液或氨水中CO2:和总氨的测定,目前化肥厂都采用量气法和酸碱滴定法分别定量.
浩瀚色谱（山东）应用技术开发有限公司采用研发的防腐专用气相色谱仪，用峰高定量。方法准确、可靠,较常规的CO_2量气法和NH_3的酸碱滴定法简单、迅速,可用做工厂的控制分析。
