Abstract:
Choosing a particular wastewater treatment method should take into account both the environment and the economy in addition to its effectiveness to prevent two crucial ecological issues that affect the entire world. One that covers the full range of potentially harmful and irreversible effects on the many ecosystems and food web components. This puts additional strain on clean water delivery systems in both rural and urban areas. To maintain development within a circular economy, additional potable water must be drawn from the available freshwater reserves to fulfill rising water demands. Therefore, the primary goal of this research is to develop an environmentally friendly technique for eliminating the dye methylene (MB) via physicochemical process that involves adsorption on magnetic charcoal. Magnetic adsorbents were synthesized by mixing 4 g of activated charcoal (AC) with 13.1795 g of FeCl3 and 6.9502 g of FeSO4.7H2O. FT-IR analysis was used to characterize the produced Fe-AC adsorbents. The magnetic AC (Fe-AC) that was created was successfully employed to remove MB from aqueous solutions. The effects of a number of variables, such as temperature, pH, adsorbent dosage, initial MB dye concentration, and contact time, were studied with regard to adsorption. These magnetic particles were recovered from the media by a straightforward magnetic process and employed as an adsorbent. Adsorption capacity increases with time and decreases as temperature rises. A UVVis spectrophotometer was used to determine how much MB was present in the solution. The maximal adsorption capacity was determined by the Langmuir isotherm model to be at 45 °C. The outcomes also demonstrate that the adsorption matches fictitious pseudo second-order kinetics. Magnetic charcoal, a new adsorbent, offers enormous promise for the removal of MB dye from aqueous solutions due to its advantages of being made affordably and having a high adsorption capacity.
