ultra-dispersed sorbent - Opis:
- This work is devoted to mine wastewater purification from metal ions, such as copper, zinc, lead, cadmium, iron, and manganese. The rationale was provided for the possibility to purify the wastewater from metal ions with nonactivated and ultra-dispersed natural sorbents. The adsorption capacity of bentonite clay from Tagan deposit and shungite from Koksui deposit of the Republic of Kazakhstan was studied on the basis of its fraction composition. It was found that the most effective method of sorbents modification was mechanical activation. The comparative studies of metal ions adsorption efficiency were carried out with mechanically activated and ultra-dispersed bentonite clay and shungite. The experiment enabled to find out that ultra-dispersed bentonite clay is prospective for use in order to deeply purify multicomponent mine wastewater. The highest degree of metal ions extraction was achieved due to 30-minutes contact of wastewater.
