Several approaches have been used to reduce the accumulation of heavy metals in aqueous solutions, including adsorption to the surface of agricultural waste. Batch studies have been performed in this study to explore the adsorption of Fe 2+ , Mn 2+  on olive pomace (OP), and moringa seed husk (MSH). Fourier transform infrared and scanning electron microscopy also characterized the prepared adsorbent. Batch adsorption studies were performed, and the effects of adsorbent chemical structure, adsorbent dosage, pH, contact time, and initial ion concentration were investigated on Fe and Mn ions sorption and mechanism in order to maximize the removal efficiency of Fe and Mn. It was shown that the removal percentage of Fe 2+  and Mn 2+  were 83% and 91%, respectively, at optimum pH 5 and optimum time of 120 min at 5 g of OP. Although the removal percentage of Fe 2+  and Mn 2+  were 80.5% and 93%, respectively, at 5 g of MSH. The pseudo-second-order model was followed by the adsorption kinetics of Fe 2+  and Mn 2+  on OP and MSH, and the Langmuir model worked well with the adsorption isotherms. Based on their adsorption/desorption processes, OP and MSH adsorbents may be regenerated by DI water more than five times. The overall adsorption power of the OP adsorbent for Fe 2+  and Mn 2+  was 10.406 and 10.460 mg/g, and the MSH was 10.28 and 11.641 mg/g for Fe 2+  and Mn 2+ , respectively.
