Embodiment 1

[0027] 1. Solubilization of extractant Et-Tol-DAPhen

[0028] In order to solubilize the insoluble extractant Et-Tol-DAPhen, the present invention tried several systems, as shown in Table 1. For single micellar solutions in typical CPE systems, such as TX-100 and TX-114, neither can dissolve the extractant. Even adding long-chain alkylimidazolium ionic liquids cannot solve the problem of dissolution. Studies have shown that the use of nonionic surfactants and cationic surfactants to construct mixed micelles can improve the solubility of the extractant, change the charge properties of the micelles, and improve the extraction efficiency. [7-8] . Here, cationic surfactants cetyltrimethylammonium bromide (CTAB) and dioctadecyldimethylammonium chloride (DDAC) were selected to construct mixed micelles with TX-114, respectively. But unfortunately, the extractant still cannot dissolve in the system. The reason may be that the extractant has a large size, strong rigidity, and stron...

Abstract

The invention discloses an application method of a hydrophobic extractant in a cloud point extraction system. The extractant is carried into the cloud point extraction system by forming an O / W microemulsion, which skillfully solves the problem of poor water solubility of the extractant. The problem of being unable to solubilize in the system has successfully realized the selective enrichment of target ions by the cloud point extraction system. The invention realizes the application of hydrophobic extractant in the cloud point extraction system for the first time, and the cloud point extraction technology can still selectively enrich the target actinide ions under the interference of many lanthanide ions, which is efficient and fast, and avoids a large amount of organic waste The production of liquid reduces environmental pollution, simplifies the post-processing process, and reduces post-processing costs. In addition, the combined use of ICP-MS can also realize the rapid and accurate detection of trace target ions, which can form a universal separation and analysis method.

Description

technical field [0001] The invention relates to the application technology of a hydrophobic extractant in a cloud point extraction system, in particular to a method for solving the application problem of an insoluble extractant in a cloud point extraction system by constructing an oil / water (O / W) microemulsion. Background technique [0002] For a long time, traditional liquid-liquid extraction has played an important role in the separation of elements. However, with the advancement of science and technology and the enhancement of people's awareness of environmental protection, exploring a greener and more efficient extraction system has become the focus of everyone's attention. Cloud Point Extraction (Cloud Point Extraction, CPE) has the advantages of safety and environmental protection, high enrichment factor, simple post-processing after phase separation, and low cost, and has received more and more attention in element separation. [1] . When the concentration of the non...
