Croatian clinoptilolite and montmorillonite-rich tuffs for ammonium removal

Clinoptilolite and montmorillonite-rich tuffs from Croatian deposits were examined to evaluate their ability for ammonium ions uptake. Both tested materials have potential for removing ammonium from waters. However, the montmorillonite-rich tuff is not as effective as clinoptilolite-rich tuff, particularly in the presence of competing Ca2+ cation. In all experiments, the clinoptilolite-rich tuff exchanged a far more ammonium compared to the montmorillonite-rich tuff.
