Abstract

The effect of some environmental ligands and certain fertilizers on the complexation of strontium with humic acid wasinvestigated colorimetrically and radiometrically. The results indicate that Na₂-EDTA, Na₃-citrate and NaCl compete to complex strontium in solution with the sequence: chloride < citrate < EDTA while Na₃-phosphate has the reverse behavior. In the case of nitrogen containing fertilizers, the results show that urea, Mg-ammonium nitrate and ammonium nitrate increase the availability of strontium to plants and microorganisms.
