Abstract
A soil for metal analysis having a high water content of 40% or more is dried up to 20% or less in water content within a short period of time. A filter paperis laid over an inner bottom surface plateof a nutsche. Powder of a super absorbent polymeris uniformly spread (filled) on an upper surface thereof. Further, another filter paperis laid thereon. A soil sample with a high water content is packed on an upper surface thereof, thereupon carrying out predrying to approximately 30% in water content. After that, the predried soil sample is added with ethanol, stirred and received in a receiving pan. The receiving panis arranged in a drying chamber. Water is supplied by a syringeto a reaction vesselhaving been filled with calcium oxide or barium oxide, thereby reacting calcium oxide or barium oxide with water. The receiving panis heated by a reaction heat generated at that moment, thereupon carrying out postdrying to make the water content 20% or less.
