Reagents for Extraction Analysis

Reagents for Extraction Analysis

Extraction in chemistry is a separation process consisting in the separation of a substance from a matrix. According to the difference solubility of various components, the reagents with high solubility of the extracted components and low solubility of impurities are selected, and the extracted components can be extracted from the mixture. The most critical factor in extraction analysis is the choice of the reagents.

There are several factors to consider when choosing reagents for extraction analysis. First, the reagents cannot react with the extracted components. Second, the reagents should have a high solubility in the extracted components and a low solubility in the impurities. Third, the reagents used should be inexpensive, readily available, non-toxic, safe and easy to recycle. Furthermore, in order to better choose the reagents, it is necessary to understand the classification of the reagents. Reagents for extraction analysis can be divided into strong polar reagents, hydrophilic organic reagents and lipophilic organic reagents. The generally used strong polar reagents are water, acidic water and alkaline water. The common hydrophilic organic reagents are methanol, ethanol, acetone and others. In addition, the frequently-used lipophilic organic reagents are ether, chloroform, benzene, petroleum ether, etc.
