摘要: Abstract The adsorption of chromium compounds from solutions by a composite polyaniline/poly ethylene glycol (PANi/PEG) was investigated in this study. Experiments were conducted batch mode under various operational conditions including agitation time, solution pH, PANi/PEG dose and initial concentration salts. Results showed that PEG at synthesizing stage has significant effect on the capacity produced for removal chromium. Morphologically, is closely dependent PEG. Maximum hexavalent experienced when 2 g/L used synthesis PANi/PEG. Removal included surface reduction reaction. optimum pH 5 equilibrium time about 30 min. Investigation isothermal characteristics high accordance with Langmuir's isotherm.
