WebAmmonium carbonate ((NH 4) 2 CO 3, AR), sodium carbonate (Na 2 CO 3, AR) and carbonic acid (H 2 CO 3) solution were used for carbonation pretreatment. Among, the 0.5 M H 2 CO 3 solution was prepared by injecting the high-purity CO 2 (99.9999%, Tianjin Sizhi Gas Co., Ltd) into deionized water until the pH value was maintained at 3.33–3.35. The carbonate ion is the simplest oxocarbon anion. It consists of one carbon atom surrounded by three oxygen atoms, in a trigonal planar arrangement, with D3h molecular symmetry. It has a molecular mass of 60.01 g/mol and carries a total formal charge of −2. It is the conjugate base of the hydrogencarbonate (bicarbonate) ion, HCO−3, which is the conjugate base of H2CO3, carbonic acid.
