The use of brown coal in Ukraine to obtain water-soluble sorbents

Purpose. To develop a method of using salts humic acids obtained from brown coal Ukraine for sorption heavy metal ions and their extraction ultrafiltration membranes. Methodology. Unique laboratory equipment has been developed to determine the capacity substances with concentration 0 20 mg/l in relation (Cu2+, Pb2+, Cd2+, Hg2+, Zn2+, Co2+) 5 mg/l. The results proximate ultimate analyzes, as well infrared optical emission spectroscopy were used assess quality coal, solution ions. Findings. Ukrainian Oleksandriia geological-industrial district contains large amount (about 80%) acid, which is basis obtaining effective water-soluble sorbents. It proved that allow binding up 99% complexes. most optimal terms selectivity Originality. possibility practical proved. As membranes, UF-20-PAN membranes are used, porous polymer films based on polyacrylonitrile pore size m, working surface area membrane 28.26 10-4 m2. Practical value. introduction technology will allow, firstly, restoring use deposits Ukraine, secondly, introducing deep treatment industrial wastewater.
