Water purification from heavy metals
Fibrous ion exchangers PANION® are effective filtering materials for removal of heavy metals: Fe(II), Pb(II), Zn(II), Cu(II), Co(II), Ni(II), Cd(II), Hg(II) and others.
Drinking water should practically not contain heavy metal ions - their maximum permissible concentrations are very small. The most common problem is the removal of ferrous ions, especially when using artesian water. Also, in some cases, it is necessary to remove ions of manganese, mercury, lead, cadmium, copper, nickel, cobalt, and chromium from drinking water. The natural waters of each specific region contain its own specific set of such ions. For example, countries of Eastern Europe - iron and manganese; countries of Western Europe - lead and nickel; large industrial centers - mercury, cadmium, chromium.
When purifying drinking water, it is necessary to preserve its natural mineral components needed by humans: sulfates, chlorides, bicarbonates, calcium, magnesium and sodium.
Ion exchangers PANION® make it possible to solve this problem.
Panion 110 — Removal of ions of heavy metals, water softening
Fibrous ion exchanger PANION 110
PANION 110 — weak-acid fibrous cation exchanger, an analogue of well-known trademarks VION, FIBAN, MION.
Applications:
- Air purification from volatile substances of base nature: ammonia, amines, alkalis etc. Panion 110 can be applied in industrial and domestic air cleaning systems;
- Water purification from the ions of heavy metals, water softening;
- Human protective means (respirators, gas-masks, protective costumes etc): removal of vapors of ammonia and amines.
