title: [Study on IR of interaction of three modified-starchs and crystallization of calcium carbonate].
abstract: Three types of CaCO3 can be synthesized through biomimetic synthesis. In the present work, carboxymethyl-starch, etherified-starch, and phosphate-starch, used as organic matrices, were studied by FTIR. The result shows that the intensity of C-O peaks of the three modified-starchs changed. In addition, the intensity of C-O peaks was weakened or vanished obviously with the increase in time. The action mechanism of the modified-starchs and CaCO3 was briefly discussed.
