Selective removal of ammonia from wastewater using Cu(II)-loaded Amberlite IR-120 resin and its catalytic application for removal of dyes.

ABSTRACT: Cationic ligand exchange is one of the most predominant mechanisms for the removal of ammonia from wastewater through complex formation. The complexation technique occurs between the metal ions loaded on the surface of Amberlite IR-120 and ammonia which is present in the medium. Cu(II)-loaded Amberlite IR-120 (R-Cu²⁺) was prepared and described using FT-IR, TGA, SEM, and EDX techniques. The prepared R-Cu²⁺ was applied for the elimination of ammonia from an aqueous solution. Different cations such as Co²⁺ and Ni²⁺ were loaded onto Amberlite IR-120 to study the impact of counter cation on the removal efficiency of ammonia. The ammonia removal percentage followed the order; R-Cu²⁺  > R-Ni²⁺  > R-Co²⁺. The effects of
