Increasing Selective Recovery of Critical Minerals in Water Filtration Polymer Membranes
Clean water is a vital resource, yet modern filtration systems produce large quantities of waste. This waste is often rich in rare critical minerals, but cannot be easily refined. This work seeks to address both issues through specialized Polymer Membranes. Membranes are relatively easy to produce, replace, and extract minerals from, making them a promising method. The main obstacles are producing membranes that can filter a target mineral, avoiding contamination of membranes, and identifying sustainable methods of extracting minerals from membranes. This study seeks to address the first concern of critical mineral selectivity while taking into consideration the other two.
