As an adsorbent of gaseous ammonia, cobalt hexacyanocobaltate (Co II 3 [Co III (CN) 6 ] 2 ) was proved to have good sorption even at high temperatures, with thermal recyclability in sorption-desorption cycles. The maximum sorption capacities evaluated with a dual-site Langmuir model are 25.2, 18.6, 8.6, and 2.1 mmol g −1 at 20, 100, 150, and 250 °C, respectively. Cobalt hexacyanocobaltate (Co II 3 [Co iii (CN) 6 ] 2 ) was proved to have good sorption even at high temperatures, with thermal recyclability in sorption-desorption cycles.
