摘要: Abstract A sensitive and selective colorimetric method for simultaneous detection removal of copper (Cu(II)) ion from contaminated water samples was developed based on the functional ligand embedded mesoporous conjugate materials. The synthesized material’s characterization also presented. materials exhibited an obvious color change colorless to dark yellow in presence Cu(II) according pH values. Also, were detected removed through naked-eye. prepared material significant upon addition even other competing ions, limit calculated be 0.15 μg/L. Excellent selectivity toward observed due a specific complex formation between organic In adsorption operation, several affecting factors, including solution pH, contact time, initial concentration, foreign ions reuses investigated. results showed that excellent capacity equilibrium reached rapidly. well fitted with Langmuir isotherms maximum by 174.76 mg/g. We claimed this study could successfully current work. present work is obviously much simpler greener than conventional comprising multistep processes. demonstrated loaded effectively regenerated using HCl acid solution, repeated use many cycles without loss, indicating good stability
