Abstract
Provided is an apparatus for dissolving noble metals. A pH adjusting unit controls pH of liquid inside a dissolution reactor in such a manner that a chlorine compound is produced. The noble metal in a noble metal-containing sample introduced into the dissolution reactor is dissolved by the chlorine compound, and the liquid evaporated from an inorganic material extraction unit is recycled to the dissolution reactor.
