ABSTRACT
OBJECTIVE:
To study the absorptive effect of activated carbon and desorptive effect of organic solvent on endotoxin.METHOD:
The effect of different pretreatment modes,time,temperature,amount of activated carbon as well as treatment time on the absorptive effect of activated carbon were analyzed using limulus reagent test.Different organic solvents and treatment time were used to study the desorptive effect of organic solvent on endotoxin.RESULTS:
Activated carbon was treated by high temperature baking or adding 0.5 mol?L-1 NaOH represented same effect in removing endotoxin.It showed that optimal time for absorption of endotoxin was 12 min and the amount of activated carbon was at 1.5%.The absorptive effect was similar under condition of room temperature and 37 ℃.The best effect of desorption achieved by using 75% alcohol as desorption reagent after 8 minutes of shaking.CONCLUSION:
The activated carbon could be used to absorb endotoxin effectively under suitable conditions and organic solvent could be used to desorb endotoxin from activated carbon.
