Abstract

Morpholinated and 8-hydroxyquinolinated silica gel were obtained via reaction of silica chloride with morpholine and 8-hydroxyquinoline, respectively. The applicability of the synthesized reagents for softening of different water samples was studied. The quality of softened water was tested by measuring concentrations of Mg2+, Ca2+ and HCO3− ions. The results show that the above reagents are suitable for water softening. The isotherms for adsorption of Ca2+ and Mg2+ were obtained.
