Spectrophotometric Measurement of Calcium Carbonate …

10/1/2013· Measurements of ocean pH and carbonate ion concentrations in the North Pacific and Arctic Oceans were used to determine calcium carbonate saturation states (ΩCaCO3) from spectrophotometric methods alone. Total carbonate ion concentrations, [CO32–]T, were for the first time at sea directly measured using Pb(II) UV absorbance spectra. The basis of the method is given by the following: …
