2.4. Batch biosorption studies
Batch mode adsorption studies for individual metal compounds
were carried out to investigate the effect of different
parameters such as adsorbate concentration, adsorbent dose,
agitation time and pH. Solution containing adsorbate and
adsorbent was taken in 250 mL capacity conical flask and agitated
at 120 rpm in a shaker at predetermined time intervals.
The adsorbate was decanted and separated from the adsorbent
using Whatman No. 41 filter paper.
