Rain is slightly acidic even in unpolluted air, because carbon dioxide in the atmosphere and other natural acid-forming gases dissolve in the water. 就算空气没有被污染,雨水也是呈弱酸性的,因为大气中的二氧化碳和其他酸性的气体会溶解在(雨)水中。
Research progress in ionic-liquid absorbent for acidic gases removal 用于脱除酸性气体的离子液体型吸收剂研究进展
Concentration Polarization of Membrane Absorption Process of Acidic Gases 酸性气体膜吸收过程中浓差极化
In this paper, the dynamic adsorption, hygroscopicity and reusability of FFC-1 ion exchange fiber for various acidic and basic harmful gases were measured in different conditions. 系统考察了不同直径及反离子形式的FFC-1聚羧酸离子交换纤维对酸碱有害气体的穿透吸附,各种温、湿度条件下的吸水率,以及作为有害气体吸附滤除材料的重复使用与再生性能。
Study on acidic gases in the regional background air in northeastern China 中国东北区域本底大气中酸性气体的研究
The quality of acidic gases is one of the key factors for the steady operation of Claus unit. 酸性气质量是硫回收装置平稳运行的关键因素之一。
Removing the acidic gases in the flue gas with lime particles at high temperature and separating the reaction product immediately benefit the operation of incinerator and improves its safety and economy. 利用石灰作吸收剂在较高温度段净化垃圾焚烧烟气中所含的酸性气体,并及时进行收尘有利于焚烧炉的安全、经济运行。
In this paper three kinds of limes which are common absorbents for acidic gases are used to absorb four kinds of typical heavy metals occurring in the incineration flue gases, namely, Cd, Pb, Zn and Cu under the temperatures of600 ℃ and800 ℃. 研究了常用的酸性气体吸收剂石灰在600℃和800℃下对焚烧烟气中常见的四种重金属Cd,Pb,Zn和Cu的吸附效果。
HCl, SO2 was main acidic gases. The gas clean mechanism was utilization of acid-base neutralization. 酸性气体主要是HCl、SO2,其净化机理是利用了酸碱中和反应。
There were many kinds of hydrogen bond acidic materials which were used to detect the hydrogen bond basic gases such as never agents, but these materials were not conductive. 虽然现目前已经研制出多种氢键酸性材料用于探测具有氢键碱性的神经毒剂,但这些材料都是不导电的。
