Patent number: 4701500Abstract: Heavy metals can be fixed to solid carriers to which an .alpha.-amino- or an .alpha.-iminohydroxamate ligand has been covalently bound. The ligand can have the structural formula ##STR1## wherein R.sub.1 and R.sub.2 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 .alpha.-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 sodiumborohydride or sodiumcyanoborohydride.Type: GrantFiled: April 30, 1985Date of Patent: October 20, 1987Inventor: Jerker Porath
