Sorption of Cm(III) and Gd(III) onto gibbsite, α-Al(OH)3: A batch and TRLFS study

Characterization of powellite-based solid solutions by site-selective time resolved laser fluorescence spectroscopy

“…It is to be expected that Gd 3+ and Eu 3+ will behave identically in the synthesis procedure. 40 Single crystal samples. A single crystal was grown from the melt of stoichiometric composition according to the formula NaGd 1−x Eu x (MoO 4 ) 2 with x = 0.001 using the Czochralski method.…”

Attenuated Total Reflection - Infrared Spectroscopy Applied to the Study of Mineral - Aqueous Electrolyte Solution Interfaces: A General Overview and a Case Study

“…The system 5-sulfosalicylic acid (5-SSA)/gibbsite is part of a broader study involving Cm adsorption onto gibbsite (Huittinen et al, 2009). Interaction of dissolved Cm with 5-SSA (Panak, 1996) and acid-base equilibria of gibbsite (Adekola et al, 2011) have been studied separately.…”

Nanogibbsite: Synthesis and characterization

“…The gibbsite (a-Al(OH) 3 , monoclinic, P21/n) structure consists of double layers of closed packed OH groups with Al atoms occupying two thirds of the octahedral interstices within the layers [11][12][13][14]. Each Al atom is octahedrally bonded to three oxygen atoms of layer A and three oxygen atoms of layer B [14,15]. Gibbsite crystals are well developed along a and b directions but show limited growth along the ''c" direction.…”

“…The kinetics of gibbsite formation showed a marked dependency on solution pH, aging, dialysis period, presence of foreign ions and temperature. Since gibbsite is an important industrial material, recently several attempts have been made to synthesize nanogibbsite particulates [11,14,21]. Although the organic phase based methods showed appealing results for gibbsite synthesis [21], the associated experimental procedures are lengthy sand cumbersome, hence we avoided this approach.…”

“…Although the organic phase based methods showed appealing results for gibbsite synthesis [21], the associated experimental procedures are lengthy sand cumbersome, hence we avoided this approach. In most of the previous methods, the nanogibbsite particulates are often contaminated with Al(OH) 3 polymorphs of different sizes in the range of about 100 nm [11,14,[22][23][24]. Therefore, the synthesis of nanogibbsite particles with an identical size, morphology, and crystal structure is a challenging task.…”
