Use | Overview cerium nitrate is a chemical substance, combustion, irritant, colorless or light red triclinic crystals deliquescence, toxic, can react with alkali. Melting point 150 °c (loss of 3 molecules of crystal water). Very soluble in water, soluble in ethanol, acid, acetone. Drying with sulfuric acid can lose the water of crystallization, weathering can make it lose two half molecules of crystal water; 200 deg C that is decomposed into cerium oxide, can react with the alkali. Purposes: can be used for the separation of cerium and other rare earth metals, phosphoric acid ester hydrolysis as a catalyst for spectral analysis of reagents, lanthanum, praseodymium, neodymium determination; Oxidants, catalysts, pharmaceuticals and the manufacture of gas lamp material. |

Abstract:
The rice seed was soaked in Ce(NO3)3 solution with concentrations from 2.5~30 mg/L for 48 h. Results showed that the germination of seed and the root growth was promoted and chlorophyll contents in the seedling increased. It probably was the soaked seeds increased absorption water rate, membrane pe

Abstract:
The effects of rare earth on biomass accumulation and Taxol synthesis and release in cell culture of Taxus chinensis were studied by electron microscopy and polyacrylamide gel electrophoresis, at the same time, the mechanism of rare earth regulating secondary metabolism was further discussed. The results showed that the appropriate amount of rare earth could promote the synthesis of Taxol, and had a certain effect on the enzyme system and Ultrastructure of cells.

Abstract:
The effect of cerium nitrate on the expression of CaM Ⅰ and PMCA1b genes in rat liver was studied by reverse transcription polymerase chain reaction. Intraperitoneal injection of high and low concentrations of cerium nitrate did not cause changes in CaM Ⅰ, PMCA1b gene expression, suggesting that the effect of cerium nitrate on calmodulin and Ca2-ATPase may only be at the post-transcriptional level.
