Abstract:
With the application of nanomaterials in seawater desalination technology increasing, the adjustable characteristics of carbon-based nanomaterials make it possible to use multiwalled carbon nanotube (MWCNT) materials in seawater desalination technology. In this study, Ni[Fe(CN) 6 ] 2 is loaded onto the inner wall of MWCNTs by the co-precipitation method to prepare MWCNTs with variable pore size, making it a switchable cage for NaCl. During the procedure, most of the Ni[Fe(CN) 6 ] 2 is transferred to the outer surface of the MWCNTs after adsorption, and NaCl is stored inside the MWCNTs (which have been proved by characterization); at the same time, Ni can improve the cell stability of Ni[Fe(CN) 6 ] 2 . The effect of adsorbent reaction time and addition amount on the desalination performance of MWCNTs/Ni[Fe(CN) 6 ] 2 has been tested. According to the results, the best desalination performance of MWCNTs/Ni[Fe(CN) 6 ] 2 is 1354.6 mg g −1 when the reaction time is 0.5 h and the addition amount is 20 mg. After 3 cycles of adsorption and desorption, its desalting performance decreased to 242.3 mg g −1 .
