L-Aspartic Acid with Dual Functions: An Eco-Friendly and Affordable Choice to Accelerate High Salinity Brine Utilization.

ABSTRACT: L-Aspartic acid (L-Asp) poses a dual function, which can affect the evaporation and crystallization process of the high-salinity brine by altering the physical or chemical properties of the salts. MSWI (municipal solid waste incineration) fly ash washing leachate, as a typical high-salinity brine, is utilized here to validate this hypothesis under the simulation guidance. Since L-Asp has stronger adsorption energy on the (110) crystal face of CaCO₃, L-Asp can facilitate the preferential growth of more valuable vaterite during the softening process (pretreatment before crystallization). Subsequently, the resulting solution undergoes a stable interfacial solar-driven crystallization process under the L-Asp, with a high salt recovery ratio of 0.14 kg m^-2 h^-1 w
