Granular Activated Carbon GAC

Which Chemicals Will Granular Activated Carbon (GAC) Adsorb?  A Quick Reference Guide.

I get asked all the time about specific chemicals and the probability of being adsorbed by Granular Activated Carbon.   Below is a quick reference guide.   Always ask your carbon supplier for the GAC Adsorption  isotherm for the chemical you want to remove.  The GAC Isotherm will show you the mg of chemical adsorbed per mg of GAC at constant temperature.   Also, bench scale testing is important as certain adsorption rates are affected by pH, soaps and by the presence of Chelating Compounds such as EDTA. Group 1: Chemicals readily adsorbed by Granular Activated Carbon (GAC) GAC commonly used to remove ... » Read More
