摘要: Aspects of the present disclosure provide composite carbon blocks with improved capacity for the removal of contaminants such as THMs (trihalomethanes) and trace VOCs (volatile organic compounds) found in water. In one aspect, a filtration matrix comprises a polymeric binder and an adsorptive media comprising activated carbon having a bulk density of 0.54 (0.57, or even 0.60) g/cc or greater. The carbon BET surface area can be 1100 (950, or even 550) m2/g or less. The polymeric binder can be ultra high molecular weight polyethylene. Also provided are methods of making filtration matrixes.
