Research Abstract

The apparent partition coefficients of trace elements including rare earth elements have been obtained using natural seashells and coral skeletons, which can be considered as representatives of natural calcium carbonate materials generated by Organisms, and the mechanisms participated during their formation processes have been examined. Some corals have been cultured and compared to the natural corals. Moreover, the rare earth element partitioning experiments for calcite/aqueous solution have been performed to examine the trace element partitioning mechanism between natural and synthetic system
