ABSTRACT
Removal of heavy metals by low cost adsorbents is effective way of heavy metal treatment. Batch experiments are generally carried out for determining kinetics, isotherms and affecting parameters. Practical application of adsorbents calls for studies on different contacting equipments. Packed and fluidized beds can be used for removal of heavy metals from wastewater. In the current investigation, packed bed, 45 mm in diameter is used for adsorption of iron and chromium from synthetic effluent. The break through time was observed to be 40 to 45 minutes for removal of these heavy metals. Ideal adsorption time was 88 to 90 minutes.
Key words: Heavy metals, adsorbent, breakthrough time, ideal adsorption time, concentration.
