Tiivistelmä
Indium is a metal that is commonly utilized in the electronic industry. Consumption of Indium has increased dramatically, but supply has not kept pace with demand. Additionally, Indium is classified as a critical raw material due to the absence of large primary sources. Recycling Indium and recovering Indium from alternate sources is essential to meeting growing demand. Seawater brines were discovered to be a significant source of Indium, and technological development is required to recover it.
The purpose of this thesis was to develop a sustainable technique for Indium recovery from brine solutions. This research focuses on the recovery of Indium by adsorption technology using 3D printed adsorption modules. The effective adsorbent for In (III) adsorption was synthesized using additive manufacturing techniques. The 3D printed TP-260 adsorbent was utilized to preconcentrate In (III) using the column adsorption method and yielded 0.97 recovery of Indium.
By offering a larger surface area, a robust structure, facile separation from adsorbed solution, and simple recovery and regeneration by acid elution, additive manufacturing (3D printed technology) gave a significant advantage in the adsorption process.
