The effect of humic acid on the formation and solubility of secondary solid phases (Nd(OH)CO3 and Sm(OH)CO3)
Antoniou, Stella; Pashalidis, Ioannis; Gessner, A.; Kumke, M. U. (2011)The formation of secondary Ln(III) solid phases (e.g. Nd(OH)CO3 and Sm(OH)CO3) has been studied as a function of the humic acid (HA) concentration in 0.1M NaClO4 aqueous solution and their solubility has been investigated ...

Spectroscopic investigations on the effect of humic acid on the formation and solubility of secondary solid phases of Ln2(CO3) 3
Antoniou, Stella; Pashalidis, Ioannis; Gessner, A.; Kumke, M. U. (2011)The formation of secondary Ln(III) solid phases (e.g., Nd 2(CO3)3 and Sm2(CO3) 3) was studied as a function of the humic acid concentration in 0.1 mol/L NaClO4 aqueous solution in the neutral pH range (5-6.5). The solid ...

Surface mechanism of the boron adsorption on alumina in aqueous solutions
Demetriou, Antri; Pashalidis, Ioannis; Nicolaides, Athanassios V.; Kumke, M. U. (2013)The adsorption of boron (boric acid) from aqueous solutions on alumina has been investigated at pH 8.0, I = 0.1 M NaClO4, T = 22 ± 3°C, and under normal atmospheric conditions. The characterization of the adsorbed species ...
