尿素工艺物料中二氧化碳测定方法的研究

摘要

The said method is of a volumetric one with advantages of not being affected by ambient temperature,time consumed short,simple operation with no longer use of highly toxic reagent such as formaldehyde and in good precision.Not only the accuracy of data analyzed is guaranteed ,but also the labor intensity is decreased and furthermore,the harm to human-being by the experiment reduced,all these have greatly contributed to the occupational health and safety and environmental protection.%本测定方法为体积法,此方法有不受环境温度影响,耗时短,操作简单,不再使用甲醛等高毒试剂,精密度好等优点。不仅保证了分析数据准确度,还降低了劳动强度,更减轻了实验对人体的伤害,在职业健康和安全环保方面有极大贡献。
