Abstract
This paper presents the ability of a low-cost sorbent, waste wood – fir bark (Abies sibirica Ledeb.) to remove of heavy metal from aqueous solution. The method of chemical modification of fir bark has been proposed to obtain this sorbent. Dynamic sorption patterns of Cu2+ cations (as example) from water solution by modified bark of fir were studied. The dynamic exchange capacity of modified bark reached 22,50 mg/g for Cu2+ cations at the inlet Cu2+ concentration of 50 mg/dm3 and at the minimum flow rate of 5 cm3/min. The dynamic exchange capacity decreased with increasing flow rate. The model Thomas was found to be suitable for describing the breakthrough curves...
