چکیده
|
For the removal of heavy metal ions adsorption is considered an environmental friendly technique. in this research work lawrencepur sand has been successfully utilized as adsorbent for the removal of cr(vi) from industrial waste effluents. effects of ph,shaking speed,contact time and amount of adsorbent were studied. ftir was used to study basic surface characteristics. different adsorption models were employed to calculate adsorption capacity. optimum conditions for cr(vi) uptake by lawrencepur sand were 3.5g/100ml adsorbent dose,ph 6,shaking speed 200rpm. it has been concluded that lawrencepur sand can be used as low cost adsorbent for removal of cr(vi) from waste water.
