WebSodium zeolite softening is the most widely applied use of ion exchange. In zeolite softening, water containing scale-forming ions, such as calcium and magnesium, passes through a resin bed containing SAC resin in the sodium form. In the resin, the hardness ions are exchanged with the sodium, and the sodium diffuses into the bulk water solution. Web31 dec. 2015 · The cobalt (II) ion-exchange process followed the Freundlich and Langmuir adsorption models as well as the pseudo-second-order kinetic model. The cobalt …
WebA zeolite containing an exchange ion such as ammonium can be mixed with phosphate minerals (such as apatite, calcium phosphate) to produce a controlled-release phosphorus fertilizer. The zeolite takes up Ca 2+ from the apatite and releases phosphate and ammonium ions into the soil: Ca 3 (PO 4) 2 + 6NH 4 -zeolite ⇋ 3Ca-zeolite + 6NH 4+ + … WebThe efficiency of zeolite for the removal of three heavy metal Cu 2+, Pb 2+ and Cd 2+ ions from a synthetic solution was considered. These three ions were chosen as abundance more pollutants that are present in industrial wastewaters.
