Abstract
Disclosed is a sulfur-doped micro zero-valent metal reducing agent containing a zero-valent metal, wherein a metal sulfide layer synthesized using a ball milling process may be formed on a surface of the zero-valent metal. In addition, disclosed is a method for preparing a sulfur-doped micro zero-valent metal reducing agent including, in a ball milling process using a ball milling apparatus composed of a jar, balls, and a body, a first step of preparing an inorganic mixture by mixing a zero-valent metal and sulfur with each other, and a second step of forming a metal sulfide layer synthesized on a surface of the zero-valent metal by putting the inorganic mixture into the jar together with the balls and performing ball milling.
