SOA are activated charcoal (AC), which can take from 6 hours, to DAYS to fully saturate to max dye uptake. Also, ultimate uptake of dyes can be quickly reached resulting in frequent sorbent changes in industrial processes.
By tuning the porosity and structure of the HPCs as well as the surface chemistry, AIMM has developed an HPC sorbent that is specifically tuned to removing dyes. AIMM’s porous carbon HPCs remove more dyes per weight of sorbent—up to 200 times more dyes, at ultrafast speeds of 5-15 seconds; lessening downtimes for sorbent changes. One customer has estimated this will double their overall process time!
Against high performance powdered AC, AIMM’s HPCs remove more dye per weight of sorbent at an ultrafast time of 5 seconds. ACs with high surface areas (roughly 1000 m2/g, via BET) were used for comparison. The HPCs are tuned for porous structure and surface chemistry to do this.

Due to HPC’s hierarchical porosity (bigger pores going into smaller pores, going into smaller pores), the dyes have fast access to HPC’s high surface area sites (see schematic below on teh bottom right). This is analogous to contaminants "travelling" through our HPCs like cars going from highways to roadways to driveways; while activated charcoal is like trying to cram a collassally large amount of cars into a tortuous pathway of pure driveways. A powdered form of AC was used that has much faster uptake than granular activated charcoal (GAC) to compare AIMM’s HPCs to the best AC in terms of dye uptake speed at 5 seconds. results of all three shown below.
Yes! HPCs bring “whiz-bang” science into their materials at the nano scale, that appear just like a powdered porous charcoal in our scale, like AC. Thus, HPCs can use the same 100 years of AC engineering—whiz-bang science without the whiz-bang weirdo material fit problems!
