Some factors influencing the wastewater treatment process were studied such as: treatment time, pH, and the concentration of Mn (II) ions from wastewater. The results showed that using magnetite nanomaterial adsorbent leads to a wastewater treatment efficiency higher than 97%. Langmuir and Freundlich models were applied to describe the adsorption process. The correlation coefficients (R2) showed that both models are applicable to the experimental data obtained.en-USAdsorptionMagnetite nanomaterialManganeseWastewater treatmentArticle10.37358/RC.20.7.8256
