EFFICACY OF LIGNOCELLULOSICS MATERIALS, ZEOLITE AND PERLITE FOR REMOVAL OF CATION AND ANIONS FROM SEA AND WASTE WATER

The adsorption of Ca, Zn, Na, Cd (II), Cr (III) and NO3- ions from sea water, industrial and urban wastewater and aqueous solutions by poplar (Populus nigra L.) 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 sea water, industrial and urban wastewater and Cd (II), Cr (III) and NO3- from aqueous solutions. Generally, Ca, Zn, Na removal efficiency of mixture of W+alpha+P+Z was reported to be higher than other adsorbents. The removal efficiency of heavy metals with W and mixture of W+alpha 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 as well as on sea water.
