文摘

MS-C-D is an efficient Ag(I) adsorbent to overcome concentrated interfering ions. Trace levels of Ag(I) can be selectively adsorbed by MS-C-D adsorbent. MS-C-D shows higher adsorption affinity and selectivity coefficient of Ag(I). MS-C-D maintains high capacity and selectivity for Ag(I) after 3 cycles.
