Imam Khomeini petrochemical co. is one of the biggest oil producer centers across Iran. Aromatic unit is one of the eleven units of corporation. Hygienic and industrial wastewaters are flow in swage system of the unit. Industrial wastewater consist a considerable volume of swage and produced in 9 different section of aromatic unit. Wastewater of this unit evacuate to the seawater without forwarding through the suitable water treatment system. With purpose of qualitative and quantitative study of aromatic unit’s wa...

This paper describes removal of Pb(II) ions from aqueous solutions using NaOH modified pine barks (Pinus nigra). Chemical modification and its enhancement effect on adsorption capacity for heavy metal treatment process have been investigated in this article. Changes of the surface properties after modification were examined by the FT-IR analysis. Maximum adsorption capacity was 49 mg/g at pH 8 and during about 180 min contact time (for 35 mg/L initial concentration with 2.5 g/L solid-to-liquid ratio) These modific...
