Preliminary study on the stannous ions removal from aqueous solutions by hydroxyapatite

Abstract

The effect of stirring times and pH of solutions on the potential of HA in removing Sn ions have been investigated. The results shown that HA powder have tendency to remove a number of Sn ions by adsorption mechanisms. The longer stirring times has given higher removal percentage of Sn ions from solutions. On the other hand, the HA filtration capability reduced at lower pH solutions.
