- Abstract
- A new method has been developed for measuring biogenic silica (amorphous) in marine sediments. It is based on the Hogbom-Urey reaction CaCO3 + SiO2 (biogenic silica) --> CaSiO3 (wollastonite) + CO2. The reaction is carried out in evacuated sealed glass tubes with added excess reagent grade calcite at 500 degrees C for 3 d. The product CO2 is measured in a calibrated manometer. The dependence of the reaction on time, temperature, product CO2 pressure, and other factors is examined. (C) 1998 Elsevier Science Ltd. All rights reserved.
