Background: The presence of many intrusive agents in a device for analyzing materials always leads to the inability of these methods in the direct analysis of complex matrices. Therefore before the device decomposition, the sample needs to be prepared during which the desired analyte is extracted, fermented and condensed and being in a position to be compatible with the parsing device. The method of dispersive liquid-liquid micro extraction treatment is one of these methods.
Methods: The collection of data from articles with dispersive liquid-liquid micro extraction analyzes by 2017 was reviewed at Elsevier's bases and Google scholar.
Findings: This method operates on the basis of a three-solenoid system in which a dispersing solvent is used to disperse the extractor solvent in the aqueous phase , and it has two steps injecting a suitable mixture of extraction and dispersing solvents into the sample containing analyte and centrifuging the mixture so that the extraction efficiency goes up. This method has been able to outperform other methods due to the low solvent extraction ( at the microliter level) , short-term fast reaching equilibrium , high enrichment factor , negative effect on the environment and compatibility with FAAS , ET-AAS , HPLC , GC methods. High interactions between the components in the food samples with organic solvents, the extraction process and the production of a well-deposited phase are used in these samples to be diluted, but it does make some changes to the inherent characteristics of the matrix.
Conclusion: This method is suitable for samples containing high concentrations of analyte. Of course, it should be noted that this method has limitations, such as the toxicity of the conventional solvent extraction that is used in this method, which is limited to the derivation of analyte with different polarization. Therefore, we must look for extraction solvents to compensate for the constraints mentioned. |
