【摘要】 利用芒硝和石灰悬浊液吸收二氧化硫来制取亚硫酸钠,对于降低亚硫酸钠生产成本(比用纯碱)无疑是一种好办法。本文包含实验过程及其应用。该法可用于较低成本脱除二氧化硫污染,并能制得一种产品而增加经济效益。更多还原

【Abstract】 The method of using sodium sulfate and lime in an aqueous emul-sion to absorb sulfur dioxide is no doubt good for reducing the productioncost of sodium sulfite(cf.soda ash).The experimental process and itsapplication are included in this paper.The method can be applied to clearpollutants of sulfur dioxide in a comparative low cost and make a productso as to increase economic benefits.更多还原
