A Study of the Adsorption of Ni(II) and Cu(II) by Clay Minerals
Adsorption Ni(II) Cu(II) Clay Minerals clay minerals kaolinite
2012/2/13
The adsorption of Ni(II) and Cu(II) on to the clay minerals kaolinite, chlorite, and illite has been investigated. The quantity of Ni(II) at pH 6 and Cu(II) at pH 5 adsorbed has been found to vary in ...
The Co-ordination of Hydrated Cu(II)- and Ni(II)-Ions on Montmorillonite Surface
Co-ordination Montmorillonite Surface optical spectra
2012/2/13
The optical spectra of Cu2+ and Ni2+ on Camp Berteau montmorillonite after lyophilization and evacuation at room temperature are characteristic for the presence of Cu(H2O)42+ and Ni(H2O)62+ in the int...
Hydroxyl Stretching Frequencies of Synthetic Ni-, Al-, and Mg-Hydroxy Interlayers in Expanding Clays
Hydroxyl Frequencies of Synthetic Mg-Hydroxy Interlayers
2011/11/17
Abstract: Interlayers were produced in montmorillonite, vermiculite and hectorite in aqueous suspensions by precipitation from metal chloride salt, by hydrolysis of metal amalgams, and by slow hydroly...
Absorption of Pyrimidines, Purines, and Nucleosides by Co-, Ni-, Cu-, and Fe(III)-Montmorillonite (Clay-Organic Studies XIII)
Absorption Pyrimidines Purines Nucleosides Montmorillonite
2012/2/21
Absorptions of purine and pyrimidine derivatives by Co- and Ni-montmorillonite at pH < 6 and by Cu-montmorillonite at pH < 3 are similar to their absorption by Ca-montmorillonite and take place primar...
