Document Type and Number:
Japanese Patent JPH0222699
Kind Code:
B2
Abstract:
Heavy metals can be fixed to solid carriers to which an a-amino- or an a-iminohydroxamate ligand has been covalently bound. The ligand can have the structural formulawherein R1 and R2 represent H or an alkyl, or may be a compound of two or more hydroxamate substituents. The carrier can be formed of polysaccharides, polygalactanes, polyacrylates or silica dioxide. The adsorbent is prepared by an a-aminohydroxamate in an aqueous solution having a pH value of 4-9 being brought into contact with an aldehyde derivative of a carrier, followed by reduction with sodium- borohydride or sodiumcyanoborohydride.
