Method for removing heavy metal from water

Abstract

A method for removing a heavy metal from water includes subjecting a microbial solution containing a liquid culture of a urease-producing bacterial strain and a reaction solution containing a manganese compound and urea to a microbial-induced precipitation reaction, so as to obtain biomineralized manganese carbonate (MnCO3) particles, admixing the biomineralized MnCO3 particles with water containing a heavy metal, so that the biomineralized MnCO3 particles adsorb the heavy metal in the water to form a precipitate, and removing the precipitate from the water.
