Detailed Product Description: | Advisory Universal Testing Center Wang TEL: 1353053612 Online QQ: 2575289065 gravimetric method including chemical analysis of rare capacity and spectrophotometry. Chemical analysis of the production process and product testing has been widely applied. 1, oxalate gravimetric method gravimetric method, long used to the constant determination of rare earth. The separation of interfering elements clean, accurate, as accurate analysis and standard analytical methods is recommended. In addition, the earth's constant moisture and Determination of ignition loss is also used Gravimetric method. 2, volumetric analysis capacity analysis for the determination of total rare earth constant, the amount of cerium and raw materials used in the smelting process (hydrochloric acid, sulfuric acid, etc.) for analysis Including complexometric titration (EDTA titration REE), redox titration (ferrous ammonium sulfate method to measure the amount of cerium), acid-base titration (hydrochloric acid, sulfuric acid concentration analysis). 3, spectrophotometry spectrophotometry for determination of trace impurities in rare earths, such as silicon, phosphorus, chloride, sulfate, etc. These non-metallic elements. 4, atomic absorption spectroscopy in the rare earth metallurgical analysis, often using air - acetylene, nitrous oxide - acetylene flame measurement non-rare earth impurities in the composition of the appropriate flame, since most elements are quantitatively be dissociated into atomic vapor, so by atomic absorption spectrometry can be quantitatively determined.
