Strontium carbonate precipitation as a sample preparation technique for isotope ratio analysis of Sr in mineral water and wine by quadrupole‐based inductively coupled plasma mass spectrometry

Abstract

The quality of the separation is only limited by the number of precipitation repetitions. Moreover, the applicability of quadrupole-based ICP-MS for the characterisation of samples with respect to their origin by means of Sr isotope ratio determination was demonstrated.

Concentration‐Gradient‐Method for sulphur and strontium isotope ratio determination by quadrupole‐based inductively coupled plasma mass spectrometry in gypsum

“…To obtain Rb‐free gypsum samples, separation techniques, described by Dronov et al, were used. Na 2 CO 3 was added to the supernatant Snt1 in order to precipitate CaCO 3 and SrCO 3 .…”

Atomic Spectrometry Update – a review of advances in environmental analysis

“…Although MC-ICP-MS would usually be used for isotope ratio analysis of natural waters, a quadrupole ICP-MS method has been published 94 for the determination of Sr isotope ratios in mineral waters and wine. To separate Sr from the interfering Rb isotopes, Sr was coprecipitated out of solution by the slow addition of a 1M Na 2 CO 3 solution.…”

New Process for the Sulfonation of Algal/PEI Biosorbent for Enhancing Sr(II) Removal from Aqueous Solutions—Application to Seawater

“…Metal removal may involve different techniques; however, sorption and biosorption processes have retained great attention for low-concentration effluents [ 7 , 8 , 9 , 10 ]. Though precipitation and flotation techniques can be used for pre-treating strontium-bearing effluents [ 11 , 12 ], it is generally useful to couple different techniques [ 13 ] for reaching high levels of metal recovery. For the specific treatment of complex solutions (such as brines and seawater), it is thus necessary to design new sorbents having high selectivity against alkaline and alkaline-earth competitor ions.…”
