Heavy Metal Eliminator

These metals cadmium, lead, tin, gallium, germanium, indium, antimony, thallium, and bismuth are grouped together as heavy metals due to common chemistry. The most common economic metals are cadmium, lead, and tin. Gallium, germanium, indium, antimony, bismuth and thallium are of less commercial interest and occurrence. These metals will form a wide variety of compounds that are cationic and anionic so a variety of different resins can be applied to their separation.

Heavy metals can be removed from neutral pH water as cations. A weak acid cation exchanger Resin is a good choice due to its high capacity and ease of regeneration. A second option is a strong acid cation exchanger Resin.

Many of these metals can be more selectively removed from solution with chelating resins like the iminodiacetic acid resin.
