1. A method of treating a fluid volume, the method comprising contacting the fluid volume with a sorbent, wherein:
- the fluid volume has an initial concentration of C6+ components prior to the contacting,the fluid volume has a final concentration of C6+ components after the contacting that is less than the initial concentration of C6+ components, andthe sorbent comprises amorphous SiO2 at a weight percent greater than 90%, wherein a relative micropore surface area (RMA) of the sorbent is greater than 10%.
