The mesoporous adsorbent was fabricated by direct immobilization of a synthesized (3-(3-(methoxycarbonyl)benzylidene) hydrazinyl)benzoic acid onto mesoporous silica monoliths and tested for its potential application of Cu(II) ions sensing and removal from wastewater. The Cu(II) bonding with ligand to enhanced color formation and capturing corresponding to formation of [Cu(II)-ligand]n+ complexes. The effective pH range for Cu(II) capturing was neutral region and the maximum sorption capacity of the adsorbent was as high as 145.98 mg/g. The new type adsorbent exhibited good recyclability for several cycles use after sensing and removal operation without deterioration in its significant performances.
