The change of the activities of the metallic ions duringextraction was examined. The interfacial tension of the system was also measuredby drop weight method. The interfacial excesses of all compounds were calculatedfrom the interfacial tension equation which is expressed in the terms of activities.The results show that H~+ and Cu~(2+) are positive adsorption but CuR_2, (HR)_2, SO_4~(2-)and HSO_4~- are negative adsorption. Key words:  extraction kinetics      activity      interfacial tension      interfacial excess      Received:  18 April 1990      Service E-mail this article Add to citation manager E-mail Alert RSS （） Articles by authors URL:  https://www.ams.org.cn/EN/     OR     https://www.ams.org.cn/EN/Y1990/V26/I4/93 1 宋其圣,沈静兰.化学试剂,1985;7(5) :297 2 Preston J S, Whewell R J.
