A biomimetic supported liquid membrane (SLM) system was employed to control the morphology of strontium carbonate. Some interesting morphologies, including rods, shuttles and spheres, can be readily generated by using citric acid, nitrilotriacetic acid and ethylenediaminetetraacetic acid as cooperative modifiers in the mineralization process, under the conditions of pH 10, 0.01% of crystal modifier and ambient temperature. Seeking the cooperative balance of the SLM, the modifier agent and its concentration is the key factor in this system. In addition, this method was successfully applied to the morphology control of other alkaline earth metal carbonates, indicating its general applicability in materials preparation.
