Preparation of a mono-disperse anion exchanger with strongly basic functional groups in the resin core or shell comprises polymerizing a monovinyl aromatic compound(s) and a polyvinyl aromatic compound(s), aminomethylating with phthalimide derivatives and reacting with chelating functional groups. Preparation of mono-disperse anion exchanger with strongly basic functional groups in the resin core or the resin shell comprises reacting monomer droplets of a monovinyl aromatic compound(s) and a polyvinyl aromatic compound(s) to give a mono-disperse, crosslinked bead polymer, aminomethylating with phthalimide derivatives and reacting to give a bead polymer and reacting with chelating functional groups. Independent claims are included for the obtained ion exchangers and heavy metal and noble metal removing processes using the exchanger.
