Electrometric investigations on formation of lanthanum molybdates as a function of pH
(Soc Brasileira Quimica, 2004-03-01)
The precise nature of the reaction between lanthanum nitrate and sodium molybdate at specific pH levels 7.6, 5.5 and 4.1 has been studied by means of electrometric techniques involving potentiometric and conductometric ...
Effect of lanthanum addition on the properties of potassium-free catalysts for ethylbenzene dehydrogenation
(2008)
The ethylbenzene dehydrogenation in the presence of steam is the dominant technology for styrene production, one of the most important high value chemicals. The most widely used industrial catalyst comprises potassium-promoted ...
Biosotption of lanthanum using Sargassum fluitans in batch system
(Elsevier B.V., 2002-12-01)
Separation and purification of lanthanum from other rare-earth (RE) elements are highly complex processes comprising several steps of extraction using organic solvents or ion-exchange resins at high costs. In order to study ...

Lanthanum cobaltite black pigments with perovskite structure
(2013-05-09)
In this work La1-xCaxCoO3 (x = 0-0.4) pigments were synthesized by the polymeric precursor method with heat treatments at 700, 800 and 900 C for 4 h. The powders were characterized by colorimetry, UV-vis spectroscopy and ...
