The results show that the optimal value of CoCl2 concentration is 0.2 mol/L and the maximum adsorbed amount is 19.674 mg/g onto this adsorbent. The adsorption capacity of phosphine onto CoCl2-modified ACF decreases with the increase of temperatures. The maximum absorbed amounts are 19.674 mg/g at 298 K, 13.537 mg/g at 313 K and 11.087 mg/g at 328 K, respectively. It is found that the Freundlich equation is more suitable for the description of phosphine adsorption process than the Langmuir equation. The isosteric heat of adsorption decreases with the increase of the surface loading on CoCl2-modified ACF, which means that CoCl2-modified ACF adsorbent has an energetically heterogeneous surface. Meanwhile, adsorptive phosphine removal performance may be a dominant of physical adsorption when the heat of adsorption is 16-24 kJ/mol, the CoCl2-modified ACF adsorbent will be one of the candidates for tail gas purification of airtight calcium-carbide furnace and recycle of phosphine.
