Abstract

PURPOSE: To obtain an inexpensive noxious metal adsorbing agent with easy handling property and excellent adsorbing capacity by using one prepared by grinding a tuff soft stone material such as Oya-ishi or the like and, thereafter, backing the resulting powdery stone material.
CONSTITUTION: A tuff soft stone material such as cut trash or the like discharged when Oya-ishi is mined and cut is used as a stock material and this stock material is crushed into a powdery form and, thereafter, baked at 150W 300°C to remove contained moisture as well as to bake off org. substances on a surface thereof and, thereby, a noxious metal adsorbing agent is prepared. The obtained adsorbing agent adsorbs and removes the noxious metal such as lead, cadmium or the like efficiency as well as can be inexpensively prepared because of utilization of cut trash or the like.
