Calculating the equilibrium constants of a Sn(II)-H2O-OH− system with allowance for precipitation

Effective adsorption of In(iii) from hydrochloric acid solution using hyperbranched polyethyleneimine and sodium chloroacetate modified weakly acidic macroporous resin

“…And the separation performance of In( iii ) on CM-HPEI-HD-1 in mixed solution with different pH values was investigated. To prevent the precipitation of Sn( ii ), 58 the pH range was studied from 1 to 2.4. The results are shown in Fig.…”
