| titleOfInvention | Process for removing heavy metals from aqueous solutions by means of ion exchange resins |
| abstract | Heavy metals, for example iron, are removed from aqueous solutions from photographic processes by passing the solutions through a bed containing a mixture of cationic and anionic exchange resins. Preferably the cationic exchange resin is a strongly acidic resin, for example in the protonated form, and the anionic exchange resin is a strongly basic resin, for example in the hydroxylated form. Preferably the proportions of cationic to anionic exchange resins in the mixture are in the range 60:40 to 40:60, the basis being by equivalents. The proces is particularly suitable for the removal of iron in the form of a chelate from the wash water from photographic development processes. |
