Removal of iodate from aqueous solution using diatomite ...

2020-4-22  Abstract In this paper, diatomite/nano titanium dioxide composite (DNTD) was used as adsorbent to remove iodate from aqueous solution under different conditions. The maximum distribution coefficient could be up to 370 mL g−1 in acidic environment. The sorption speed is very fast and satisfies the pseudo-second-order equation. The sorption isotherm is well described by the Freundlich model ...
