    • 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 paper 5 is laid over an inner bottom surface plate 2 of a nutsche 1. Powder of a super absorbent polymer 6 is uniformly spread (filled) on an upper surface thereof. Further, another filter paper 7 is 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 38. The receiving pan 38 is arranged in a drying chamber 37. Water is supplied by a syringe 43 to a reaction vessel 42 having been filled with calcium oxide or barium oxide, thereby reacting calcium oxide or barium oxide with water. The receiving pan 38 is heated by a reaction heat generated at that moment, thereupon carrying out postdrying to make the water content 20% or less.
    • 将含水量高达40%以上的金属分析用土壤在短时间内干燥至含水量的20%以下。 将滤纸5放置在螺母1的内底板2上。超吸收性聚合物6的粉末在其上表面上均匀地铺展(填充)。 此外,在其上铺设另一个滤纸7。 具有高含水量的土壤样品被填充在其上表面上,然后预干燥约30%的含水量。 之后,将预干燥的土壤样品加入乙醇,搅拌并接收在接收盘38中。接收盘38布置在干燥室37中。水通过注射器43供应至填充有钙的反应容器42 氧化物或氧化钡,从而使氧化钙或氧化钡与水反应。 接收盘38被该时刻产生的反应热加热,进行后干燥,使含水率在20%以下。
