Alkali-treated starches as a new class of templates for CaCO3 spherulite formation: Experimental and theoretical studies

As an ecological and environment-friendly building material, sticky rice mortar has attracted the attention of many researchers. Amylopectin is the most important organic matter of it, which can improve the mechanical properties and durability of sticky rice mortar by inducing mineralization of calcium carbonate ( CaCO3 ). However, amylopectin induced formation of CaCO 3 has not been reported. In this paper, mineralization of CaCO 3 induced by gelatinized amylopectin is investigated. For comparison, the different morphologies of CaCO 3 are studied in the presence of Mg 2+ , Fe 3+ . Moreover, these CaCO 3 products with different morphologies are used to clean the waste water. The results indicate that gelatinized amylopectin is conducive to formation of pumpkin-like vaterite. It forms uniform rod and dumbbell-shaped calcite in the presence of Mg 2+ , form calcite with stepped depressions in the presence of Fe 3+ . The adsorption of Pb(II) can reach extremely high level (1445.86 mg g −1 ) with the rod-like calcite.
