METHOD OF PRODUCING A MATERIAL FOR HEAVY METAL ABSORPTION OR FOR ANALYTICALLY DETECTING HEAVY METALS

摘要

The invention concerns a method of producing a material for heavy metal absorption or for analytically detecting heavy metals, in particular uranium and radium. The method comprises the following steps: preparing a material which contains nitrogen organically bonded in a polymer; treating the material with potassium permanganate in a basic solution; and treating the material with ferrous hydroxide in a basic solution. The resultant material is suitable for use in a method of analytically detecting heavy metals and heavy metal isotopes in a sample fluid and for a method of purifying contaminated fluids.
