Zusammenfassung:To provide a treatment agent for removing heavy metals such as selenium, cadmium, arsenic and a lead compound, and a harmful substance such as hydrogen gas, and a waste water or gas treatment method using the treatment agent.SOLUTION: A treatment agent contains a tectosilicate mineral which is an aluminosilicate mineral containing radical sulfur in a crystal structure and has a basic structure of (AlSiO4)X as an essential component. As the aluminosilicate mineral containing the radical sulfur in the crystal structure, there is at least one kind of minerals selected from lazurite, Lapis Lazuli, azure, an ultramarine pigment, synthetic lazurite, synthetic ultramarine and Afghanite or a solid-solution mineral of lazurite and sodalite, noselite and hauynite.SELECTED DRAWING: None 【課題】セレン、カドミウム、ヒ素、鉛化合物等重金属類や水素ガス等の有害物質を除去するための処理剤を提供すること、及びこの処理剤を用いた廃水又は気体の処理方法を提供する。【解決手段】結晶構造内にラジカル性硫黄を含むアルミノシリケート鉱物で、(AlSiO4)Xの基本構造を有するテクト珪酸塩鉱物を必須成分とする処理剤である。結晶構造内にラジカル性硫黄を含むアルミノシリケート鉱物としては、青金石、ラピスラズリ、瑠璃、ウルトラマリン顔料、合成青金石、合成ウルトラマリン、アフガン石又は青金石と方曹達石・黝方石・藍方石との固溶体鉱物から選ばれる1種類以上の鉱物がある。【選択図】なし
