Measurement method of inorganic germanium content in carboxyethylated germanium sesquioxide

Abstract

The invention relates to the technical field of chemical product testing, in particular to a measurement method of inorganic germanium content in carboxyethylated germanium sesquioxide (Ge-132). Hydrochloric acid is used for distilling and separating inorganic germanium (IV) ions in a carboxyethylated germanium sesquioxide solution, then phenylfluorone-CTMAB- is adopted on the separated inorganic germanium (IV) ions for developing, and a spectrophotometric method is used for measurement. The measurement method of the inorganic germanium content in carboxyethylated germanium sesquioxide is reliable.

Description

technical field [0001] The invention relates to the technical field of chemical product testing, in particular to a method for measuring the content of inorganic germanium in carboxyethyl germanium sesquioxide (Ge-132). Background technique [0002] In recent years, my country has become the world's largest germanium production, processing and export unit. The germanium series products produced, such as high-purity germanium dioxide, zone-melted germanium ingot, germanium single crystal, carboxyethyl germanium sesquioxide, etc. have 60 More than 100% are exported to the United States, Germany, Japan, Belgium and other countries. Human research on carboxyethyl germanium sesquioxide began in the late 1980s, especially in Japan, where there are many studies on the production process and application fields of carboxyethyl germanium sesquioxide. Carboxyethyl germanium sesquioxide (Ge-132) has a history of more than 20 years since the early 1990s. Some domestic and foreign enterpr...

Problems solved by technology

Carboxyethyl germanium sesquioxide (Ge-132) has a history of more than 20 years since the early 1990s. Some domestic and foreign enterprises began to develop carboxyethyl germanium sesquioxide (Ge-132) in March 1990 It has been put into the market one after another, and has a wide range of applications in the fields of medical and health care products. At present, many units at home and abroad are producing carboxyethyl germanium sesquioxide (Ge-132). With the extension of the domestic and foreign germanium industry chain and the The demand for carboxyethyl germanium sesquioxide in domestic and foreign markets, the application field of carboxyethyl germanium sesquioxide is constantly developing, in the future, carboxyethyl germanium sesquioxide The demand for carboxyethyl germanium sesquioxide will be greatly increased, and manufacturers using carboxyethyl germanium sesquioxide as raw materials to produce other products are increasing. However, since inorganic germanium dioxide in carboxyethyl germanium sesquioxide is a harmful substance, it needs to be controlled and detected Its content, although there are some test methods, such as paper chromatography, phenylfluorone-spectrophotometry, column separation-ICP-AES method, etc., but the repeatability and precision are not very good, so there is no stable and reliable method at present.
