Сорбційні властивості вуглецю, активованого ортофосфорною кислотою

The adsorption activity of activated carbon was found to depend on conditions of chemical treatment of precursor with orthophosphoric acid. As a precursor, dried apricot seeds were milled to a fraction of 0.25–1 mm. The surface area and value of pore capacity of carbon material increase with H3PO4 c...

Zusammenfassung:The adsorption activity of activated carbon was found to depend on conditions of chemical treatment of precursor with orthophosphoric acid. As a precursor, dried apricot seeds were milled to a fraction of 0.25–1 mm. The surface area and value of pore capacity of carbon material increase with H3PO4 concentration. As a result, a mesoporous carbon with 0.9–1.23 cm3/g pores value was prepared, giving adsorption activity for methylene blue 310–350 mg/g and methyl orange 365–370 mg/g.
