The results of FTIR of CaCO3 samples at the absorption peak of 4000-500 cm-1 identified the functional groups of Ca-O, C-O, -CH2, and O-H. CaCO3 samples can absorb light at wavelengths of 237.1 nm, 251.5 nm, and 289.7 nm, which have an energy band gap of 3.91 eV. Thus, using this simple calcination method, the CaCO3 sample …
Calcium carbonate occurs in nature in several forms like limestone, chalk, marble etc. it can be prepared by passing carbon dioxide through slaked lime or by the addition of sodium carbonate to calcium chloride. Ca (OH) 2 + CO 2 → CaCO 3 + H 2 O. CaCl 2 + Na 2 CO 3 → CaCO 3 + 2NaCl. Excess of carbon dioxide should be avoided …
