Experimental study on the fractionation of yttrium from holmium during the coprecipitation with calcium carbonates in seawater solutions
calcium carbonates seawater Y/Ho ratios covalency
2017/8/10
The partitioning of Y and Ho between CaCO3 (calcite and aragonite respectively) and seawater was experimentally investigated at 25°C and 1 atm. Both Y and Ho were observed to be strongly partitioned i...
New preconcentration technique of Zr, Nb, Mo, Hf, Ta and W employing coprecipitation with Ti compounds: Its application to Lu-Hf system and sequential Pb-Sr-Nd-Sm separation
coprecipitation Ti compounds Lu-Hf Pb-Sr-Nd isotope analysis preconcentration
2017/8/10
A new preconcentration technique of Zr, Nb, Mo, Hf, Ta and W has been invented employing coprecipiation with Ti compounds. Silicate samples were digested by HF with addition of Ti. Subsequent drying w...
Coprecipitation of Iron and Aluminum during Titration of Mixed Al3+, Fe3+, and Fe2+ Solutions
Aluminum Hydrolysis Iron Oxidation Potentiometric titration
2011/11/30
Abstract: Potentiometric titration analysis was used to examine the hydrolysis behavior of Fe2+ Fe3+, and Al3+ in pure solution and in mixture, in order to evaluate the potential for coprecipitation a...
