The increasing importance of lithium in the production of electronics and energy storage systems has resulted in a considerable increase in its value over the past three years. The demand for lithium continues to grow, and the extraction of lithium from associated brines is becoming a promising and cost-effective method. The present study focuses on the use of membrane technology, specifically a multilayer membrane modified with 4′-amino-benzo-15-crown-5-ether (4AB15C5), to extract high-purity lithium from oil and gas field wastewater. This innovative approach not only provides a new source of revenue for oil producers, but also addresses environmental sustainability by reducing the negative impact of lithium extraction processes. The selective binding capacity and molecular
