Adsorption of some toxic elements from water samples on modified activated carbon, activated carbon and red soil using neutron activation analysis

Adsorption of some toxic elements from water samples on modified activated carbon, activated carbon and red soil using neutron activation analysis

A simple and sensitive method for the determination of some metalloids and heavy metals in water samples is presented. The method is based on the preconcentration of the attachment of chelating functionalities with metalloids and toxic metals irreversibly and targeted towards toxic metals adsorbed...
