An experimental investigation on drying kinetics of calcium carbonate
Calcium carbonate is a versatile mineral with diverse industrial applications. Drying is a necessary processing step in preparation of calcium carbonate product. Deep knowledge of drying kinetics is required in order to design an appropriate dryer. The main aim of the present study was to investigate the drying kinetics of calcium carbonate, experimentally. Thirteen empirical correlations with ...
متن کاملProtein-Mediated Precipitation of Calcium Carbonate
Calcium carbonate is an important component in exoskeletons of many organisms. The synthesis of calcium carbonate was performed by mixing dimethyl carbonate and an aqueous solution of calcium chloride dihydrate. The precipitation product was characterized by means of scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD), and Fourier transform infrar...
متن کاملStrain-specific ureolytic microbial calcium carbonate precipitation.
During a study of ureolytic microbial calcium carbonate (CaCO(3)) precipitation by bacterial isolates collected from different environmental samples, morphological differences were observed in the large CaCO(3) crystal aggregates precipitated within bacterial colonies grown on agar. Based on these differences, 12 isolates were selected for further study. We hypothesized that the striking differ...
متن کاملEffect of the Experimental Parameters on Calcium Carbonate Precipitation
In this study, calcium carbonate crystals were obtained by mixing of calcium chloride and sodium carbonate in the presence of biopolymer, carboxymethyl inulin (CMI). The effect of the feed rate of reactant and the initial [Ca] concentration was investigated. The produced calcium carbonate (CaCO3) crystals were characterized by scanning electron microscopy (SEM), Fourier transform infrared spect...
متن کاملPrecipitated Calcium Carbonate Nano-Microparticles: Applications in Drug Delivery
Calcium carbonate (CaCO3) is an abundant mineral that has several uses in paper [1], Portland cement [2] and steel making [3], as agricultural input for soil modification [4], and food additive in soy milk and dairy products. Due to its high biocompatibility, CaCO3 is also employed in many pharmaceutical (anti-acid, dietary supplement for child and postmenopausal women), biological (scaffolds f...
