“…However, it has a higher specific surface area, higher solubility, higher dispersibility and smaller specific gravity compared to calcite and aragonite, so it is anticipated to be used for various intentions [33][34][35][36][37]. Due to its poor thermal stability and difficulty in obtaining an extremely special and excellent property, the preparation of vaterite is also a hot topic at present [38,39]. At the same time, using waste as a calcium source and CO 2 as a carbon source, prepared CaCO 3 products are usually calcitic or partially contain calcite and cannot be used to obtain vaterite CaCO 3 .…”

In the salt lake industry, large amounts of steamed ammonia liquid waste are discharged as byproducts. The conversion of the residues into high value-added vaterite-phase calcium carbonate products for industrial applications is highly desirable. In this research, the feasibility of preparing vaterite-phase CaCO3 in different CaCl2-CO2-MOH-H2O systems using steamed ammonia liquid waste was studied in the absence of additives. The effects of initial CaCl2 concentration, stirring speed and CO2 flow rate on the composition of the CaCO3 crystal phase were investigated. The contents of vaterite were researched by the use of steamed ammonia liquid waste as a calcium source and pure calcium chloride as a contrast. The influence of the concentration of CNH3·H2O/CCa2+ on the carbonation ratio and crystal phase composition was studied. The reaction conditions on the content, particle size and morphology of vaterite influence were discussed. It was observed that single vaterite-phase CaCO3 was favored in the CaCl2-CO2-NH4OH-H2O system. Additionally, the impurity ions in steamed ammonia liquid waste play a key role in the nucleation and crystallization of vaterite, which could affect the formation of single-phase vaterite. The obtained results provided a novel method for the preparation of single vaterite particles with the utilization of CO2 and offered a selective method for the extensive utilization of steamed ammonia liquid waste.

“…When Ca is eluted by adding sucrose to seawater, the sucrose acts as a chelating agent to form Ca–sucrate, which is a calcium–sucrose complex, leading to an increase in the pH (Eq. (2)) [32] , [34] , [35] . According to Kim et al [32] , when Ca is dissolved by adding sucrose to seawater, the reaction enabled by the Mg in seawater (Eq.…”

“…Many researchers have previously reported gaseous CO 2 capture and CaCO 3 production techniques. − However, the utilization of CO 2 in atmospheric air for CaCO 3 production has been little reported. Seawater is a well-studied material for CO 2 sequestration because it is economically feasible and contains sufficient Ca 2+ (about 10 mM). − Although a high pH is required for the dissolution of CO 2 , raising the pH of seawater to above 10 causes the precipitation of Mg(OH) 2 as an impurity. , In this study, we conducted CO 2 capture from atmospheric air with a pH below 10 by adding NaOH to seawater and sequestering CO 2 in the form of CaCO 3 . NaOH can be produced by the electrolysis of NaCl obtained from evaporated waste seawater.…”

Carbon capture, utilization, and storage (CCUS) are widely recognized as a promising technology for mitigating climate change. CO 2 mineralization using Ca-rich fluids and highconcentration CO 2 gas has been studied extensively. However, few studies have reported CO 2 mineralization with atmospheric CO 2 , owing to the difficulty associated with its low concentration. In seawater, the biomineralization process promotes Ca accumulation and CaCO 3 precipitation, assisted by specific organic matter. In this study, we examined the conversion of atmospheric CO 2 into CaCO 3 in seawater using shell powders (Pinctada fucata, Haliotis discus, Crassostrea gigas, Mizuhopecten yessoensis, Turbo sazae, and Saxidomus purpurata). Among the six species, the shell powder of S. purpurata showed the highest rate of CaCO 3 formation and recovery of CaCO 3 . NaClO treatment test revealed that the organic matter in the shells enhanced the CO 2 mineralization. All materials used in this study, including atmospheric CO 2 , seawater, and shells, are economically feasible for large-scale applications. Using shell powder for CO 2 mineralization in seawater embodies an innovative technological advancement to address climate change.
