Pomegranate peel waste in the forms of raw biomass, biochar and activated carbon has been explored as adsorbents in water treatment. This review examined and discussed published works between 2008 and 2024 that focused on the utilization of pomegranate peel waste adsorbents with emphasis on preparation strategies, characterization techniques and applications. The thermal and chemical activation have shown to improve the structural and chemical properties of the resultant adsorbent materials to effectively adsorb various pollutants such as dyes, heavy metals, organics, inorganic nonmetals, and pharmaceuticals from water. The performance was compared and the avenues for future research was highlighted to shed insight into the potential of pomegranate peel adsorbents for environmental protection.

This review highlights the prospects of pomegranate peel as effective adsorbents for water pollutants removal. The papers published from 2008 to first quarter of 2024 were categorized and analyzed to shed insight into preparation strategies, adsorptive characteristics and future directions in this research area. This paper aims to fit into the growing body of knowledge, with special emphasis on different routes of synthesis and performance, which to the best of our knowledge is still absent in the open literature.
