A novel DEEA/AEP biphasic absorbent is used to absorb [Formula: see text]. After phase separation, only one phase enriched with the absorption product is sent into the mineralization system, then reacts with [Formula: see text] to produce [Formula: see text] at normal temperature and pressure. The effects of temperature, Ca/C and dispersion of the system were investigated, and cyclic utilization experiment was also conducted. The process was characterized and analyzed by Thermal gravimetric analysis (TGA), X-ray diffraction (XRD), and nuclear magnetic resonance (<sup>13</sup>C NMR).
