- Abstract
Effect of porous structure of carbon sorbents, obtained by alkaline thermal activation of ethanol-lignin of abies wood,on the methylene blue and the vitamin B12 sorption was studied. It was sown that their sorption capacity for vitamin B12 depends on the content of mesopores with width 2,00–3,61 nm and formethylene blue – on the content of micropores with width 1,06 – 1,95 nm. The isotherms of sorption of the studied marker substances on sorbents with different porous structure were compared and their differences were discussed
