To provide a pretreatment method for metal analysis, measuring a metal concentration more easily, safely and accurately without any interruption of a metal analysis by a silicon component.
A pretreatment apparatus for metal analysis 1 and the pretreatment method using the same has: a pH adjustment means 2 for adding acid to an alkali solution sampled from an alkali solution tank 50 housing the alkali solution containing the silicon component; a solid phase extraction means 3 capable of bringing a solution pH-adjusted by the pH adjustment means 2 into contact with a chelate resin or a chelate fiber to eliminate a metal from the solution; an alkali cleaning means 4 for supplying an alkali cleaning liquid to the solid phase extraction means 3, which has captured the metal, to clean the chelate resin or the chelate fiber; and a metal eluting means 5 for supplying an eluting agent to the alkali-cleaned chelate resin or chelate fiber to elute the metal from the solid phase.
