Removal of cadmium from aqueous solution by natural and thermally activated dolomite
Removal of Cd(II) from aqueous solution by natural and thermally activated dolomite was investigated. Maximum activation temperature and maximum adsorption capacities were determined as 700 degree C for 2 hours and 1.02 mg g super(-1) for natural dolomite, but 64.93 mg g super(-1) for thermally acti...

| Zusammenfassung: | Removal of Cd(II) from aqueous solution by natural and thermally activated dolomite was investigated. Maximum activation temperature and maximum adsorption capacities were determined as 700 degree C for 2 hours and 1.02 mg g super(-1) for natural dolomite, but 64.93 mg g super(-1) for thermally activated dolomite at 25 degree C, respectively. Equilibrium contact time of cadmium was determined as 1 hour. Adsorption of Cd(II) on dolomite conforms to Langmuir's isotherm. |
