摘要
本文讨论了ｐＨ值、油内比Ｒｏｉ、乳水比Ｒｅｗ及混合强度等因素对液膜分离、浓缩铜的影响，用正交法设计出液膜分离铜的各相关因素。实验表明；用液膜法取代金属螯合物萃取法分离、浓缩钢是行之有效的。
In the course of research,the writer kept some green shade tolerance plants in the living quarters of a Guiyang dweller and measured the sulphur content of their leaves and the SO2 contents of air.After three years of cultivation,he screened out those species that can clear or tolerate the SO2 indoors most effedtively.It is suggested to ust a suitable combination of such plants to improve the quality of dwelling environment.
