Zusammenfassung:	PROBLEM TO BE SOLVED: To remove a specific element at a higher speed.SOLUTION: A specific element removal method has a step for adding zeolite to a processing object solution, a step for adding coagulant to the processing object solution, and a step for removing precipitates of the processing object solution added with the zeolite and the coagulant. As the coagulant, for example, organic coagulant of a polyacrylamide system, aluminum sulfate, or the like can be used. As a flocculation aid, bentonite, active carbon, or the like can be further used. In addition, as a pH adjusting agent, sodium carbonate, ferric chloride, or the like can be used.
