Abstract
In this study the removal of Mn (II) ions from wastewater using magnetite nanomaterial was investigated. 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 lead 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.
Highlights
The industrial wastewaters polluted with heavy metal ions, which are toxic, is a huge environmental issue [1]
Where: Co- represents the initial concentration of Mn(II) ions, mg/L; Ce- represents the equilibrium concentration of Mn(II) ions, mg/L; V - represents the volume of the wastewater, L; W - represents the amount of the magnetite nanomaterial, g
3.1.Effect of pH The removal of Mn(II) ions was studied at two pH values (8 and 11.5), and the results are shown in concentration of 1.00 mg/L the removal efficiency increases with the increase pH from 91.0% to 93.0% (Figure 1b)
Summary
The industrial wastewaters polluted with heavy metal ions, which are toxic, is a huge environmental issue [1]. Heavy metals ions affect seriously human health if they are entering in the human body [2-5]. The sources of heavy metal ions pollution are industrial effluents from metal plating and finishing, rubber processing, mining, agriculture and many others [6]. This category of pollutants has toxic actions for our bodies because of their bioaccumulation in the tissues [7-10]. According to the NTPA 001/2002 standard which contains the limits of loading with pollutants of the industrial and domestic wastewater discharged in the natural environment, the concentration of manganese ions should not exceed 1.00 mg/L. Many methods are used for depollution of industrial wastewater, but some of them are not effective for removing manganese ions or they may be too expensive
