Abstract
The possibility of recovery of Cu, Zn and Co from highly mineralized acetat e-ammonia soil extracts is investigated. Optimum sorption conditions are de termined. The influence of foreign ions on the completeness of the sorption is studied. It is shown that free filling of the measuring cuvette with th e 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 t heir total contents are obtained. (C) 1999 Elsevier Science B.V. All rights reserved.
