Adsorption of Cr(VI) from aqueous solution by adsorbent …
After 180 min, solution was centrifuged and the residual Cr(VI) content of the supernatant solution was measured. For desorption purpose, NaOH solution (0.5 N) was added to adsorbent and shaken at 45℃ for 180 min. Finally, the solution was centrifuged and the residual concentration of Cr(VI) ions in the solution was determined.
Introduction of CIL Process
In this way,the desorption solution is composed of 1% sodium hydroxide and 0.1% sodium cyanide aqueous solution. The desorption time is 24-72h at atmospheric pressure of 85-95 C.

What Are the Differences Between CIP and CIL?
Carbon-in-pulp (CIP) is the sequential leach then absorption of gold from ore. During the CIP stage, pulp flows through several agitated tanks where sodium cyanide and oxygen have been added to dissolve gold into solution. In the absorption stage, this solution flows through several agitation tanks containing activated carbon.
