In this study, the quantity of ammoniumion was much more than that of nitrate ion.
2
A study on ion exchange kinetics and equilibrium isotherms of ammoniumion on natural Turkish clinoptilolite (zeolite) was conducted using a batch experiment technique.
3
Ammoniumion exchange from aqueous solution using clinoptilolite zeolite was investigated at laboratory scale.
4
This is probably because ammoniumions are competitive inhibitors, causing decreased reactivity for glutamine residues.
5
Surprisingly, monovalent sodium or ammoniumions, positioned in the product metal site, lowered the activation barrier.
