The results of adsorption-desorption of p fractions indicated that the adsorption capacity was strong, the chemical adsorption was dominant, and the sediments was a source of p.Accordingly, we concluded that the wuliangsuhai lake was in the moderate pollution level, and the sediments as a source could desorb p in natural aquatic environment.
Mines of the united states developed heap leaching technology to recover precious metals from low-grade heaps of ore using cyanide solutions, adsorption onto activated carbon and recovery us cortez heap leach in 1969 in nevada as the birthplace of modern gold heap leaching kappes, 2002.
The adsorption process is easily reversible.The downside to this is in applications where internal temperatures exceed the thresholds of the absorbing substance, it can partially regenerate, expelling moisture back into the air and causing the packet to leach or leak.
Competitive adsorption studies for cos in the presence of cs 2, and h 2 s were also conducted.Tpd analysis was used to identify sulfur-containing products on the carbon surface, and the results indicated that h 2 s, cos and so 2 were all evident in the effluent gas generated from the exhausted cu-co-kac.
