Toxicology | 1 h NMR spectra of rat urine at 0.2 and 2 mg/kg body weight of stomach nitrate showed an increase in glucose content within 0-8 h, the concentrations of succinic acid and citric acid decreased slightly. An increase in glucose levels indicates a decrease in renal tubular glucose reabsorption capacity, which is similar to the nephrotoxic drugs sodium chromate and mercuric chloride, and a decrease in urinary citric acid concentrations. It suggests that doses of 0.2 and 2 mg/kg may cause renal tubular acidosis. The decrease of succinic acid concentration indicates that the introduction of Lu3 may directly affect the tricarboxylic acid cycle system. However, the taurine content in the urine of rats did not increase at the dose of 30.2 mg /kg of Lu(NO3), which indicates that this dose has not caused significant damage to the liver. However, the Taurine Content in urine of rats at the dose of 32 mg /kg of Lu(NO3) was slightly increased, indicating that the liver may have been affected by lu3. Among them, the concentration of metabolites in urine of rats with a dose of Lu(NO3)30.2 mg /kg body weight returned to the level before medication between 16 and 24 h, and the concentration of other metabolites had no obvious change. This indicates that the 0.2 mg /kg body weight dose of the nitrate can not cause irreversible damage to the body. |
Application | CerMet nitrate can be used to prepare nanomaterials, etc. Examples of applications are as follows: A method for preparing rare earth phosphonium phosphate nanomaterials by chemical precipitation method comprises two steps of synthesis and purification, and the specific preparation process is as follows: 1) synthesis: first, Lu2O3 is dissolved in nitric acid, in which the molar ratio of Lu2O3 to nitric acid is 1:70, and Lu2O3 reacts with nitric acid to form a solution of Lu(NO3)3; then, 400g of diammonium hydrogen phosphate was dissolved in 700ml of secondary distilled water to obtain diammonium hydrogen phosphate solution. Then, the secondary distilled water was added to dilute the cerium nitrate solution to pH = 1, when the solution is heated to near boiling, slowly drop 100ml of diammonium hydrogen phosphate solution and constantly stir the solution. After obtaining a white suspension, stop heating and continue stirring the solution, cool the solution to room temperature to obtain a white suspension solution; 2) purification: The white suspension solution obtained in step 1) is centrifuged at 5000r/min for 10 minutes, and the white precipitate is obtained after pouring out the supernatant, and then the precipitate is cleared with secondary distilled water, another 10 min separation at 5000r/min After repeated centrifugation for 3-5 times until the pH of the supernatant liquid is 7, the easily water-soluble ions attached to the precipitated particles are washed off to obtain the purified precipitate; the purified precipitate was then placed in a conventional platinum crucible and baked in a box-type resistance furnace at 1000 ° C. For 5 hours to obtain a dry powder, I .e., a rare earth phosphonium nanomaterial. The Rare Earth phosphonium phosphate nanomaterial prepared by the invention has a melting point higher than 2000 ℃, a Mohs hardness of 4-7.5, and the rare earth phosphate crystal is tetragonal crystal system with a body-centered cubic structure, acid phosphonium nanomaterials are chemically stable and are not corroded by most chemicals including nitric acid and hydrochloric acid. Compared with the prior art, the invention has simple preparation process, mild reaction conditions, simple operation, easy realization and amplification, low cost, low energy consumption, and good chemical properties of the prepared rare earth phosphonium phosphate nano material, high purity. |
