Sorption of cyanocobalamin (vitamin B12) by silochrome C-120 of various graininess levels was studied under dynamic conditions. It was shown that the low-grained sorbent provided marked increasing of the cyanocobalamin sorption rate and enabled the use of the sorbent thin layers at high rates of the solution supply.
