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...

Heavy metal pollution is very important problem in waste water pollution around industrial area. Cupper has been used in many industries with civilisation period and a lot of water sources were contaminated by dissolved component of cupper metal. It has incredible effect on the micro-organisms and also other living organisms in water environment. For this reason, copper content of industrial wastewater must be decreased to the limits given in the international regulations. There are many methods may be used for he...
