Case Study

Dioctadecyldimethylammonium (DODMA) as a Key Ionic Liquid for Thorium Extraction and Separation in Nuclear Fuel Cycle Applications

Zhang, Fang, et al. Separation and Purification Technology 282 (2022): 120111.

This study explores the use of dioctadecyldimethylammonium (DODMA) as a cationic component in novel ionic liquids (ILs) for the extraction of thorium (Th(IV)) from nitric acid solutions. By combining DODMA with N,N-dialkyl-diglycolamide (DGA) anions, a highly effective extractant was synthesized, enabling the simultaneous extraction and solidification of Th(IV) ions. This process forms self-assembly (SA) solids at the aqueous-organic phase interface, significantly enhancing the extraction efficiency.
The novel DODMA-based ILs demonstrated exceptional performance, achieving over 99% extraction of Th(IV) in a one-step process. Spectroscopic techniques such as SEM, EDS mapping, XPS, FT-IR, and ESI-HRMS confirmed the successful formation of [DODMA]+[DGA·Th(NO3)4] as the extracted solid. Additionally, the ILs exhibited excellent selectivity for Th(IV) over other metal ions, with separation factors of up to 3470 for Th/Eu and 1980 for Th/U, showcasing their potential for thorium extraction in the nuclear fuel cycle.
This approach not only provides an efficient strategy for the separation of thorium from lanthanides and uranyl ions but also opens the door for similar methods to be applied in the extraction and enrichment of plutonium (Pu(IV)) in the nuclear industry. The study highlights the potential of DODMA-based ionic liquids in advancing nuclear material processing technologies.

DODMA in the Extraction and Solidification of Uranium (VI) from Sulfate Leaching Liquor

Zhang, Fang, et al. Journal of Environmental Chemical Engineering 11.2 (2023): 109279.

This study investigates the use of Dioctadecyldimethylammonium (DODMA) based ionic liquids ([DODMA]+[DGA]-) for the extraction and solidification of uranium (VI) from real leach solutions. The novel bifunctional ionic liquids, synthesized by combining DODMA with N,N-dialkyl-diglycolamide (DGA) anions, facilitate a one-step extraction process in sulfuric acid medium. The extraction achieved more than 99% uranium enrichment, with uranium ions forming a solid phase at the biphasic interface.
Spectroscopic analyses including XPS, FT-IR, ESI-MS, and TGA confirmed the coordination between uranyl ions and the carbonyl groups of the DGA anion. The ionic liquids demonstrated excellent selectivity for uranium, with separation factors of 280 for U/Fe and 117 for U/V, and minimal interference from key ions like Fe(III) and V(V).
This strategy allows for uranium extraction without the need for back-extraction, precipitation, or other complex operations, making it a promising, sustainable approach for uranium recovery. The method is advantageous for its simplicity, high selectivity, and fewer operational steps compared to traditional methods. The DODMA-based ionic liquids present a highly effective solution in uranium hydrometallurgy and could be further explored for other heavy metal recovery processes.

Dioctadecyldimethylammonium Bromide (DODMA) Modified Palygorskite for Enhanced Adsorption of Anionic Dyes

Sarkar, Binoy, et al. Applied Clay Science 51.3 (2011): 370-374.

This study explores the modification of Australian palygorskite using Dioctadecyldimethylammonium Bromide (DODMA) and octadecyl trimethylammonium bromide (ODTMA) to enhance its adsorption capacity for the anionic dye Orange II. The modified palygorskites were characterized by nitrogen adsorption to assess their surface and pore structure. At concentrations equivalent to twice the cation exchange capacity (CEC), DODMA-modified palygorskite demonstrated a high adsorption capacity of 92 mg/g, while ODTMA-modified palygorskite showed 88 mg/g at 25 °C.
Both modifications significantly improved the dye adsorption, with DODMA-modified palygorskite outperforming ODTMA in the long run. The adsorption of Orange II was controlled by electrostatic attraction and van der Waals interactions across varying concentrations. Factors such as adsorbent quantity, temperature, pH, and mixing time were optimized, with 2 CEC materials reaching equilibrium more slowly than 1 CEC materials. Notably, the neutralization of negative surface charges by DODMA and ODTMA facilitated the dye's adsorption, enhancing the material's ability to attract the negatively charged dye anions through cationic interactions.
This modification strategy demonstrates the potential of organo-palygorskites as effective adsorbents for wastewater treatment, specifically for the removal of anionic dyes. DODMA-modified palygorskite provides a promising material for environmental remediation applications.
