| Abstract: | The chemical composition of sewage sludge ash(SSA) was tested,and initial SSA was modified to increase the uptake capacity of heavy metal ions before its application.In the batch experiments,parameters studied include the effect of contact time,solution pH value and temperature.Both Langmuir and Freundlich models described Cu(II) sorption process adequately.The estimated equilibrium adsorption capacity of acidified SSA to Cu(II) was 7.78mg/g with the optimized conditions. |
