查询词典 primary adsorption

At the heavy metal concentration of 3-4ppm, our study on adsorption capacity, adsorption selectivity of montmorillonite, illite and kaolinite to Cu〓、 Pb〓、 Zn〓、 Cd〓、 Cr〓 shows that the adsorption capacity is mainly determined by the capacity of exchangeable cations and the adsorption capacity of the three clay minerals decreases in this sequence: montmorillonite ＞＞ illite＞kaolinite. It is found that clay minerals have obvious adsorption selectivity to various heavy metals. Montmorillonite exhibits a stronger affinity to Cr〓 and Cu〓 while kaolinite and illite sorb Cr〓 and Pb〓 more effectively. At the same heavy metal concentration, adsorption amount of clay minerals to heavy metals increase with increasing pH value of the solution.

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.
