摘要：

The possibility of recovery of Cu, Zn and Co from highly mineralized acetate-ammonia soil extracts is investigated. Optimum sorption conditions are determined. The influence of foreign ions on the completeness of the sorption is studied. It is shown that free filling of the measuring cuvette with the concentrate does not contribute significantly to the total analysis error. The data on the fraction of mobile forms of Cu, Zn and Co relatively to their total contents are obtained. (C) 1999 Elsevier Science B.V. All rights reserved.
