Optimization of Lead Ion Removal from Sewage Using a Two-phase Aqueous Filtration System
A PEG600 and (NH4 )2SO4 two-phase aqueous filtration system was used in lab for studying the removal of lead ions from waste water .Based on the analytical data obtained from atomic absorption spectrometry ,a response surface methodology was applied to optimize the technology .The optimal processing conditions included 40.25％ on volume fraction of PEG600 ,0.17 g · mL -1 of (NH4 )2SO4 ,pH at 2.55 ,and temperature at 40.28 to render a lead removal rate of 87. 47％ .
