Possibility of using carbon material based on apricot stones in the hemoperfusion process

Abstract

Physico-chemical properties of carbonized apricot stones (AS-850) activated by steam for two hours at 850C were investigated by different methods: SEM/EDAX, low-temperature nitrogen adsorption, methylene blue adsorption studies. The obtained material was tested as a sorbent with respect to blood toxicants in preliminary studies on hemoperfusion. The results indicated the prospect of the sorbent AS-850 to be used for blood purification form toxins, e.g.: maximal sorption degree reached 80% for alcohol and 62% for sodium barbiturate.
