Fouling of carbon, regeneration and Elution Gold
02-04-2016· Fouling of carbon, regeneration and Elution. In all plant circuits, the carbon activity quickly deteriorates from stage to stage but the reasons why it should do so are complex. It is known that the carbon activity is enhanced by lower pH, higher temperature; the presence of Ca2*, Mg2*, Na*; and by small particle size.

2% NaOH, is pumped to the elution column and is pre-heated by the solution leaving the column. The temperature is further raised by a steam heat exchanger. After stripping the gold from the carbon, the solution is partially cooled in the incoming heat exchanger and further cooled to below its ambient boiling point in a cooler heat exchanger.
GC Column Selection Guide Sigma-Aldrich
Our GC column polarity scale can be used for column selection because it allows multiple columns to be compared easily, because all P.N. values are relative to both squalane (0 on the scale) and SLB ®-IL100 (100 on the scale). Choose: Non-Polar GC columns for non-polar compounds (such as alkanes) that contain 1) only carbon and hydrogen atoms, and

Elution Wikipedia
In analytical and organic chemistry, elution is the process of extracting one material from another by washing with a solvent; as in washing of loaded ion-exchange resins to remove captured ions.. In a liquid chromatography experiment, for example, an analyte is generally adsorbed, or "bound to", an adsorbent in a liquid chromatography column. . The adsorbent, a solid phase (stationary phase
