A highly selective mesoporous composite adsorbent is proposed for simultaneous detection and removal of Cu(II) ions in natural waters. The adsorbent offered a simple procedure in ultra-trace Cu(II) sensing optically without using high tech instruments. The data also revealed that the adsorbent exhibited high sorption capacity (182.15 mg/g) and extreme high selectivity in high concentration ionic competition. Moreover, the present adsorbent was successfully applied to the determination, removal and elution Cu(II) ions in environmental samples.
