摘要：
The impact of sodium azide, as an inhibitor of biochemical reactions in aqueous solutions, on its interaction with activated carbon (AC) and on the characteristics of equilibrium adsorption of fulvic acids (FA) on AC has been studied. It was shown that additions of sodium azide during FA adsorption on AC under equilibrium conditions do not completely inhibit the biological activity in the system solution FA-AC. Sodium azide interacts with the AC surface changing the equilibrium adsorption characteristics of the system.
