摘要: Abstract Highly selective mesoporous adsorbent design is necessary for detection and removal of toxic metals from drinking water with high efficiency cost-effective. The was fabricated by direct immobilization a synthesized (3-(3-(methoxycarbonyl)benzylidene) hydrazinyl)benzoic acid onto silica monoliths tested its potential application Cu(II) ions sensing wastewater. Specific nitrogen donor atoms containing novel ligand transformed the ion-sensing systems optically remove stable assemblies complexation mechanism. bonding to enhanced color formation capturing corresponding [Cu(II)-ligand] n + complexes. variation pH, contact time, limit initial concentration parameters were measured in sorption experiments. data revealed that new type able capacity extreme selectivity ionic competition. Therefore, offered simple procedure such low-level without using sophisticated instruments. effective pH range neutral region maximum as 145.98 mg/g. exhibited good recyclability several cycles use after operation deterioration significant performances. can be used effectively sensitive efficient wastewater treatment.
