Lanthanum is often used as LaNi5-based hydrogen-storage alloys and nickel–metal hydride rechargeable batteries in hybrid automobiles. Lanthanum is added to ferrous alloys (to.

    Magnesium silicate functionalized with tetrabutyl ammonium dihydrogen phosphate was developed as a new adsorbent for La(III) removal from aqueous solutions. The functionalized material was characterized by Fourier transform infrared spectroscopy, scanning electron microscopy, energy dispersive X-ray analysis, and determination of the specific surface area ( m2g–1).   Foiling Phosphate: A Look at Lanthanum Chloride Use in the Aquarium. By Daniel Knop. First published as an online bonus to the the November/December issue of CORAL Magazine. In the last two decades, phosphate has come to be recognized as one of the central challenges of the reef aquarium hobby.

For example, it has been reported that lanthanum carbonate can be prepared by a reaction between Na 2 CO 3 and LaCl 3 in aqueous solutions. We notice that lanthanum ion possesses strong ability to bind hydroxide ion when the pH value of Cited by:

Sigma-Aldrich Online Catalog Product List: Lanthanum Salts. Lanthanum is a chemical element with the symbol La and atomic number It is a soft, ductile, silvery-white metal that tarnishes slowly when exposed to air and is soft enough to be cut with a knife. It is the eponym of the lanthanide series, a group of 15 similar elements between lanthanum and lutetium in the periodic table, of which lanthanum is the first and the ciation: /ˈlænθənəm/ ​(LAN-thə-nəm).

The number of electrons in each of lanthanum's shells is [2, 8, 18, 18, 9, 2] and its electron configuration is [Xe] 5d 1 6s 2. The lanthanum atom has a radius of pm and a Van der Waals radius of pm. Lanthanum was first discovered by Carl Mosander in In its elemental form, lanthanum has a silvery white appearance.

Lanthanum(III) Sulfate Hydrate is a moderately water and acid soluble Lanthanum source for uses compatible with e compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal sulfate compounds are readily soluble in water for uses such as water treatment, unlike fluorides and oxides which tend to be insoluble.

Lanthanum oxide, also known as lanthana, chemical formula La 2 O 3, is an inorganic compound containing the rare earth element lanthanum and oxygen.

It is used in some ferroelectric materials, as a component of optical materials, and is a feedstock for certain catalysts, among other al formula: La₂O₃. An inversion procedure to derive coarse-grained ion–ion interaction potentials for lanthanoid chloride solutions is performed.

Explicit-solvent molecular dynamics simulations are carried out for two binary salts in aqueous solution, Nd 3+ Cl − and Dy 3+ Cl −.The radial distribution functions obtained from simulations are then used to define effective short-range pair by: 5. Search term. Advanced Search Citation Search.

Search. Features of electroflotation recovery of poorly soluble lanthanum compounds from aqueous solutions containing sodium salts were experimentally determined and studied for the first time. The role was identified that anionic, cationic, and nonionic surfactants added to various supporting electrolytes (sulfate, chloride, carbonate, nitrate) play in the efficiency of electroflotation recovery of Cited by: 3.

Uses. 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 has also shown use as a filter aid and an effective num chloride is also used in biochemical research to block the activity of divalent cation channels, mainly calcium al formula: LaCl₃.
