PROBLEM TO BE SOLVED: To provide a method for manufacturing an environmental purification agent that can adsorb (absorb) cations and anions and remove them by ion-exchange, whose removal effect on various ions is high, and whose material costs and manufacturing costs can be more reduced considerably than those in a conventional method. SOLUTION: Provided is the method for manufacturing an environmental purification agent preferable as a soil cleaning agent or a water-cleaning agent, wherein a mechanical distributed processing is performed on an artificial zeolite powder at a temperature of about 30 to 55°C (liquid temperature) for 20 to 60 minutes in an acid aqueous solution where pH is controlled within a scope of about 1.0 to 5.0, after the solution is solated (turned into slurry), the solution is subjected to still standing to obtain a product as a gel object (spongy solid matter: network structure object), and the gel object is usually used after it is crushed and classified.
