Sorption capacity of dispersed pine wood towards formaldehyde was determined from its 0.142 mol/l solutions at t=20 oC. Grinding dust from pine wood processing accumulated as a waste of furniture enterprise with a particle size of 125-250 μm was used as a sample of dispersed wood. Kinetic curve of formaldehyde sorption testified that equilibrium is reached after 30 min. The effect of speed of mixing of the system as well as that of the sorbent/sorbate ratio on the value of formaldehyde sorption were determined. The maximal value of sorption capacity of the sorbent based on dispersed pine wood came to 28,5 mg/g that allows considering it as a “green” sorbent for industrial toxicants capture.
