Heavy metal ions removal from aqueous solutions using carbon aerogels and xerogels
Journal Title: CHEMIK nauka-technika-rynek - Year 2014, Vol 68, Issue 6
Abstract
Carbon aerogels and xerogels were obtained by polycondensation of resorcinol and formaldehyde in the aqueous solution using potassium hydroxide and cetyltrimethylammonium bromide (CTAB) as the catalyst. Synthesised materials were activated and their effectiveness in adsorption of heavy metals ions (nickel, copper and zinc) from aqueous solutions was tested. Obtained results show essential influence of synthesis conditions, activation method and metal ion kind on adsorption capacity of tested materials. Carbon aerogel and xerogels were characterized by similar or better (in some cases) effectiveness of nickel, copper and zinc ions removal than commercial activated carbons.
