Radiochemical study of leaching of zinc from soil

Problems of the extraction of zinc from soil with solutions of alkaline earth chlorides, sodium and ammonium acetate, EDTA and aqueous solutions of HClO₄ or NaOH with low ionic strength at various pH has been studied using radiotracer⁶⁵Zn. The strong influence of pH on extraction from chloride, acetate and aqueous solutions has been proved. No difference due to the counter ions in chloride extractants has been observed. The distribution coefficient of zinc between soil and the aqueous phase was not influenced by the V/m ratio.
