Speciation of some trace elements in water samples after preconcentration on activated carbon by neutron activation analysis

A new filtering column has been developed on the covalent attachment of chelating functionalities to simple, highly hydrophilic adsorbent material,which can then complex heavy metal ions irreversibly and targeted towards toxic metals removal. The capacity of the chemically modified sorbent (modifie...
