The Adsorption of Zinc(II) from Aqueous Solution on Modified Diatomite

Article Preview

Abstract:

The removal of Zn (II) ions from aqueous solution was studied using raw diatomite and MnO2 modified diatomite samples at different adsorption parameters such as contact temperature, contact time, initial metal ions concentration and dosage of diatomite. The results showed that modified diatomite had a better adsorption than raw diatomite; adsorption increase with increase of time and then become almost stable, appropriate time is 15 min; adsorption increase with increase of dosage of Mn-ditomite, adsorption reached up to 95.7-97.2 % at 0.8-1.0g/mg dosage of Mn-diatomite to Zn (II) .
