چکیده
|
The cr (vi) adsorption characteristics of platanus orientalis leaves and their ash were examined as afunction of contact time, initial ph and metal ion concentration. batch adsorption experiments wereperformed. the effects of ca2+, mg2+, na+ and k+ on adsorption were studied. the effect of this adsorbenton cod in wastewater showed that 2g/l of adsorbent caused increase of 110mg/l and 76mg/l cod indeionized water in 120 minutes for platanus orientalis leaves and their ash , respectively. the maximumremoval took place in the ph range of 6-7, contact time of 60 minutes and initial concentration of2mg/l. studies showed that the freundlich adsorption model better fitted with the results than langmuirwith r2 > 0.85. the study showed platanus orientalis leaves ash was more favorable than living ones aswell as in removing chromium from the aqueous solution.
