چکیده
|
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 (il/msnps) was used for adsorption/removal of manganese dust (mn) from workplace air by solid phase adsorption method (spam). 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. moreover, mn particles were become absorbed/removal from artificial air by il/ msnps at 80 oc. the mn particles separated from column of il/msnps by irrigation of nitric acid solution (2 ml of 0.3 m) 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. ultimately, for validation, spike of mn particles (bag 1 li) and icp was used for dynamic system.
