Аннотация

Heavy metal especially nickel (Ni(II)) is the most pernicious kind of pollution since it is both poisonous and difficult to break down in nature and can cause many human disorders and diseases. The monitoring and removal of Ni(II) ions optically is required to enhance the quality of the water and make it appropriate for drinking as well as other uses around the residence. Therefore, the goal of the current work was to synthesize ligand imprinted composite adsorbent (MCA) and utilize it as an adsorbent to monitor and remove Ni(II) ions from the water. Based on the findings gathered, the MCA that was synthesized had a large particle size with a high surface area even after the ligand impregnation. The MCA was enhanced significantly in color with the contact of Ni(II) ion with limit detection at 0.35 µg/L. The maximum level of Ni(II) ions was eliminated (99%) when the pH was adjusted to 5.50. The Langmuir model was also used to study the adsorption equilibrium data and the maximum adsorption capacity was 167.55 mg/g. Additionally, the method can selectively detect and remove Ni(II) even in the presence of diverse metal ions. Overall, the MCA offers an ideal platform for the on-site monitoring and removal of heavy metal ions, especially in resource-limited areas.
