Implications for the Ballast Hypothesis [37] In its original form, the ballast hypothesis, based on correlations between POC and mineral fluxes into sediment traps in the deep ocean, suggests that fluxes of POC to the deep sea may be determined by the flux of minerals, and that calcium carbonate is a more efficient ‘‘carrier’’ of POC than biogenic silica [Armstrong et al, 2001 ‘‘natural’’ source of calcium carbonate than the reagent grade calcium carbonate of the previous experiment In addition, we investigated for the first time the impact of biogenic silica on aggregates to see if organic mattersilica interactions differ significantly from organic mattercalcium carbonate interactions, as implied by the Interactions between diatom aggregates, minerals, particulate 2017年11月1日 The calcium concentration (C Cal ) was determined by the titration method using EDTA standard solution as follows [14, 38]: (1) adding V s of solution to be tested into a mixture containing (PDF) Methods for Calcium Carbonate Content Measurement2022年9月20日 Abstract Standard Reference Material (SRM) 915c Calcium Carbonate is certified as a chemical substance of known purity It is intended for use in the calibration and standardization of procedures for calcium (Ca) determinations employed in clinical analysis and for routine critical evaluation of the daily working standards used in these proceduresCertification of Standard Reference Material® 915c Calcium Carbonate
