Definitions
- the present invention is a process for the preparation of novel chelating resins based on crosslinked bead polymers which are prepared from (meth) acrylic compounds with aminoalkyl groups and / or aminoalkyl nitrogen heterocyclic groups as functional groups which have a high absorption capacity for heavy metals.
- ion exchangers have been used to remove valuable metals and heavy metals such as tin, cobalt, nickel, copper, zinc, lead, uranium, bismuth, vanadium, platinum group elements such as ruthenium, osmium, iridium, rhodium, palladium, platinum and precious metals Gold and silver used in particular from aqueous solutions.
- chelating resins are preferably used in addition to cation or anion exchangers.
- chelating resins for removing heavy or valuable metals is described, for example, in R. Hering, Chelating Ion Exchange, Akademie Verlag, Berlin, 1967, pages 150 to 157. Can be mentioned u.a. Chelate resins with iminoacetic acid groups. Chelating resins in many cases show a significantly higher selectivity for heavy metals than, for example, cation exchangers with strongly acidic sulfonic acid groups.
- the common ion exchangers absorb heavy metals from aqueous solutions at pH> 4. At pH values less than about 4, the selectivity of chelating resins for heavy metals decreases because their functional groups are protonated. However, the removal of heavy metals from solutions or suspensions having strongly acidic pH's in the range of about 4 to about 1 is of considerable technical interest.
- the limitation of the degree of halomethylation of the bead polymer also limits the amount of aminomethylpyridine groups in the chelate resin and thus the exchange capacity of the chelate resin.
