Column experiment and simulation on multi-species cation exchange reactive transport

Cation exchange is one of the major reactions in polluted soil.Laboratory experiment was employed in a vertical soil column to test conservative solute transport and reactive solute transport,respectively.Hydrogeochemical simulation software PHREEQC was applied to simulate the conservative solute transport and reactive solute transport of K +,Ca2 +,Na +,Mg2 +.Good comparison of experimental and simulation results indicate that the software can effectively simulate cation exchange and solute tran...
