The effects of nZVI concentration, pH, and initial concentration of Cu 2+ have been studied. Cu 2+immobilization increased from 59.10% to 98.10% as the nZVI concentration increased from 0.2 to 2.0 g/1. The adsorption kinetics of Cu 2+ ions was fitted to a pseudo-second order model and both Langmuir and Freundlich isotherms fit experimental data. SEM-EDX indicates that slightly porous and fragile particles were formed due to the corrosion on the nZVI surface. 2016-03-21T04:42:10Z 2016-03-21T04:42:10Z 2012 Article Environment Protection Engineering, vol.38 (3), 2012, pages 119-131 0324-8828 http://epe.pwr.wroc.pl/2012/3_2012.html http://dspace.unimap.edu.my:80/xmlui/handle/123456789/41159 10.5277/EPE120311 en Wroclaw University of Technology |
