Precautions for lithium extractant

In the process of lithium extraction, the selection of suitable extractant is the key. The choice of extractant should follow several basic principles to ensure the efficiency and safety of the extraction process:

The extractant should have good selectivity, that is, it should have good dissolution of the solute to be extracted, and other solution components should be as insoluble or less soluble as possible to ensure the directivity of the extraction.
The extractant should have excellent physical properties, because the physical properties of the extractant will affect the extraction operation.
Chemical stability is also an important consideration. The extractant should have good chemical stability to avoid chemical reactions such as corrosion, polymerization, and decomposition, and ensure the safety of operation.
Extraction speed is also a factor to consider, and the extractant should be able to complete the extraction process in a relatively short period of time to improve the economics of the chemical process.
Economic practicality is also an important consideration. Although the price of the extractant is not necessarily proportional to the effect, its cost-effectiveness should be considered when selecting.
Safety is an indispensable consideration. The extractant should be non-toxic, non-irritating, high flash point, non-flammable, and weak in volatility to reduce safety risks.
Anti-extractability is also an important consideration, that is, the extractant should be able to achieve effective conversion of the extracted material from the organic phase to the aqueous phase when the extraction conditions are changed.
In addition, in actual operation, the following points should be paid attention:

Before using the separatory funnel, check for leakage to ensure the safety and accuracy of the experiment.
Extraction operation includes adding extractant, shock extraction, static stratification, liquid separation and other steps, each step needs to be carefully operated to ensure the extraction effect.
