Gadolinium hafnate (GdHfO₃) has been studied extensively in the past decade, due to its unique properties such as high dielectric permittivity and low dielectric loss. GdHfO₃ can be used in many high-end electronic devices, including high-k dielectric non-volatile memory and radio frequency applications. However, the high availability of gadolinium ions in GdHfO₃ pose a serious challenge for their recycling. Despite extensive studies on the separation of gadolinium from other elements in GdHfO₃, there is still a need for an efficient and environmentally friendly method for the separation of gadolinium from other elements.
In this study, an effective method for separating gadolinium from GdHfO₃ has been developed based on adsorption properties of silicone. Silicone exhibits strong adsorption and selective extraction of gadolinium ions in the presence of other elements. Silicone has several advantages over other methods of separation, including its high selectivity, high efficiency, and low cost. In this study, a systematic study was conducted to investigate the feasibility of using silicone for the separation of gadolinium from other elements in GdHfO₃.
The silicone-adsorbed gadolinium was then analyzed using a combination of inductively coupled plasma-mass spectrometry (ICP-MS) and atomic absorption spectroscopy (AAS). The results indicated that the silicone-adsorption method was able to effectively isolate gadolinium with a recovery rate of up to 99%. Moreover, the silicone-adsorption method was able to separate gadolinium from other elements in a very short time (less than 1 hour).
The results of this study suggest that the silicone-adsorption method is an effective and environmentally friendly approach for separating gadolinium from other elements in GdHfO₃. The method is simple and can be implemented quickly and easily. Furthermore, the results also indicate that the silicone-adsorption method is highly selective and efficient, and has the potential to be used for large scale separations. This study demonstrates a practical and effective separation procedure that can be used for the separation of gadolinium from other elements in GdHfO₃.
Overall, the silicone-adsorption method presented in this study shows great promise for the effective separation of gadolinium from GdHfO₃. The method is effective, economical and environmentally friendly, making it a viable solution for separating gadolinium from other elements in a wide range of electronic applications. Furthermore, the method is simple, quick and easy to implement, making it a practical method for large-scale separations. In summary, the silicone-adsorption method is a viable and reliable method for separating gadolinium from GdHfO₃.
