Efficacy of lignocellulosic materials for Removal of Cation and Anions from Industrial and Urban Wastewater
2016 - IRG/WP 16-50321
The adsorption of Ca, Zn, Na, Cd (II), Cr (III) and No3 ions from industrial and urban wastewater and aqueous solutions by poplar (Populusnigra) sawdust, cotton linter, zeolite and expanded perlite were examined on the basis of a batch adsorption technique. The results revealed that application of sawdust, cotton linter, perlite and zeolite are effective in improving elimination of Ca, Zn, Na ions from industrial and urban wastewater and Cd (II), Cr (III) and No3 from aqueous solutions. Generally, Ca, Zn, Na removal efficiency of mixture of W+α+P+Z was reported to be higher than other adsorbents. The removal efficiency of heavy metals with W and mixture of W+α were reported to be higher than other adsorbents. Also the results indicated that adsorbents were effective on total dissolved solids (TDS) removal from petrochemical and rural wastewater.
