Chronic effect of manganese exposure to humans caused the dysfunction of nervous system. An applied sorbent based on hydrophobic ionic liquid passed on mesoporous silica nanoparticles was used for adsorption/removal of manganese dust (Mn) from workplace air by solid phase adsorption method. In bench scale set up, 5 mL of standard solution of nitrate and oxide of Mn (0.2-5 mg L-1) was used for generation of manganese dust in pure air by drying procedure, and then was passed through column of IL/MSNPs by SKC pump with flow rate of 200-500 mL min-1 by SKC pump. The Mn particles separated from column of IL/MSNPs by irrigation of nitric acid solution before determined by F-AAS/ET-AAS. In optimized conditions, the adsorption capacity of MSNPs and IL/MSNPs for Mn removal from air in batch system (1 Li) was obtained 118.5 mg g-1 and 216.2 mg g-1, respectively.
