Effect of humic acid on the solid phase stability of UO2CO 3
(2009)
The stability of UO2CO3 has been studied as a function of the humic acid concentration in 0.1M NaClO4, in the weak acidic pH range (4.5-5) under CO2 atmosphere. The solid phase under investigation has been prepared by ...
A simplified determination of uranium in phosphate rock and phosphogypsum by alpha-spectroscopy after its separation by liquid-extraction
(2012)
A relatively rapid, economic and robust procedure is described for the radiometric analysis of uranium in phosphate rock and phosphogypsum. The analysis is performed by alpha spectroscopy after pre-concentration and ...
The effect of natural organic matter on the formation and solubility of M(OH)4 solid phases
(2014)
In this study the formation of M(OH)4 solid phases (e.g. Th(IV), Ce(IV) and Zr(IV)) has been investigated as a function of the natural organic matter (NOM) concentration in 0.1 M NaClO4, in the pH range between 2 and 5, ...
The effect of humic acid on the formation and solubility of secondary solid phases (Nd(OH)CO3 and Sm(OH)CO3)
(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 ...
Alpha radiometry of uranium in surface and ground waters by liquid scintillation counting after separation of the radionuclide by cation exchange
(2008)
The alpha radioactivity of surface and ground water samples has been determined by liquid scintillation counting (LSC) after chemical preparation of the samples by cation exchange using the Chelex 100 resin. The method ...
Spectroscopic investigations on the effect of humic acid on the formation and solubility of secondary solid phases of Ln2(CO3) 3
(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 ...
Thorium determination in water samples by liquid scintillation counting after its separation by cloud point extraction
(2011)
The aim of this study is the separation and pre-concentration of thorium from aqueous solutions by cloud point extraction (CPE) and its the radiometric determination by liquid scintillation counting (LSC). For CPE, tributyl ...
Uranium determination in water samples by liquid scintillation counting after cloud point extraction
(2010)
The aim of this study is the radiometric determination of uranium in waters by liquid scintillation counting (LSC) after pre-concentration of the element by cloud point extraction (CPE). For CPE, tributyl phosphate (TBP) ...
Competitive adsorption of boric acid and chromate onto alumina in aqueous solutions
(2014)
The competitive adsorption of boric acid and chromate from aqueous solutions by alumina has been investigated by spectrophotometry at pH 8, ionic strength = 0.0, 0.1 and 1.0 M NaClO4, T = 22 ± 3°C and under normal atmospheric ...
Acid mine drainage treatment with dunite
(2010)
This paper reports the efficiency of dunite as an alternative alkalinity generating material and adsorbent for the passive treatment of acid mine drainage (AMD). The acid neutralization capacity (ANC) of dunite has been ...
