What is Lanthanum(III)chloride used for?
One application of lanthanum chloride is the removal of phosphate from solutions via precipitation, e.g. in swimming pools to prevent algae growth and other wastewater treatments. It is used for treatment in aquariums, water parks, residential waters as well as in aquatic habitats for the prevention of algae growth.
Lanthanum Chloride (LaCl3)has also shown use as a filter aid and an effective flocculent. Lanthanum chloride is also used in biochemical research to block the activity of divalent cation channels, mainly calcium channels. Doped with cerium, it is used as a scintillator material.
In organic synthesis, lanthanum trichloride functions as a mild Lewis acid for converting aldehydes to acetals.
The compound has been identified as a catalyst for the high pressure oxidative chlorination of methane to chloromethane with hydrochloric acid and oxygen.
Lanthanum is a rare earth metal that is very effective at preventing build up of phosphate in water. In the form of Lanthanum Chloride a small dose introduced to phosphate laden water immediately forms small flocs of LaPO4 precipitate which can then be filtered using a sand filter.
LaCl3 is especially effective in reducing very high phosphate concentrations.
