Cu(II) and Zn(II) adsorption capacity of three different clay liner materials
(Elsevier, 2014-08)
Sorption of Cu(II) and Zn(II) on three natural clays meeting the international requirements for use as liners was evaluated by means of batch tests. The purpose of this research was to determine the retention capacities ...
Uptake of acid black 210 dye by organo montmorillonite clay minerals
(European Journal of Chemistry, 2013-12)
Two clays rich in montmorillonite were modified and used as adsorbents. The clay minerals were modified with hexadecylpyridinium cation (HDP+) in order to obtain organomontmorillonites,which were used for retaining acid ...
Removal of Mn(II) and Cd(II) from wastewaters by natural and modified clays
