Sequential extraction of aragonite, calcite and dolomite from eastern Mediterranean sediments Abstract – A novel sequential extraction method for carbonates (CASEX) has been developed to differentiate between aragonite/calcite and dolomite. Dolomite can be reliably quantified as shown by the extraction of a prepared standard of known mineral ...
Uniform, hierarchical aragonite precipitated calcium carbonate stacked from nanoparticles was synthesized. The tainted Mg influence on resultant PCC purity was averted via D-glucose extraction of dolomite constituent calcium and subsequent precipitation using CO 2. The as-synthesized PCC was characterized using SEM, XRD, …

the age of the aragonite. Sequential extraction of successive fractions of CO 2 unveiled the effect of detrital material on the 14C ages, and showed that the first CO 2 extract represents the least contaminated 14C fraction that provides the best approximation for the true 14C age (which includes the lake's reservoir age).
