Wastewater treatment and reuse is a critical issue, researchers are trying to find for cheap and reasonable advances. Adsorption is the most important strategy to evacuate heavy metals. Adsorption happens when particles diffused within the liquid stage for a period of time using the force radiating from an adjoining surface. Nickel and eosin yellow removal from industrial wastewater is considered utilizing manganese ferrite (MnFe2O4), nano particles (Nps), extracted by a co-precipitation strategy at room temperature. The variables examined are the contaminant concentration, weight, pH and contact time. Adsorption isotherm models is examined. The results reveal that the nano manganese ferrite could be adopted as a great adsorbent for the evacuation of nickel and eosin yellow from contaminated water. It is shown that the particle removal rate is diminished with an increment in initial concentration. Also, it shows as the pH increases in the water, the higher the percent removal of the contaminants. Then, it is discovered that as the adsorbent dose is increased from 1 to 3 g/l, the removal of Ni+2 increases from 37% to 60%. The removal of eosin yellow increases from 12% to 28% with an increment within the adsorbent dose from 1 to 4 g/l. The results show that adsorption using nano particles is physiosorption (physical sorption) that occurs at room temperature. The results also revealed that (MnFe2O4), nano particles was a promising adsorbent for removal of Ni ions from industrial wastewater.
