Özet:

 


The increase of
industrial activities has accentuated environmental pollution problems causing
the deterioration of several ecosystems with the accumulation of many
pollutants, such as toxic metals. The present work proposes the use of a white
rot fungi (Phanerochaete chrysosporium) immobilized on bentonite as a new
sorbent in trace metal determination. The procedure is based on the biosorption
of Cu(II) and Cd(II) ions on a column of bentonite loaded with dried, dead
fungi components prior to their determination by atomic absorption
spectrophotometry. The effects of pH, amount of solid phase, eluent type and
volume of the sample solution, flow rate of solution on the retention of the
metal ions have been studied. The optimum pH values of quantitative sorption
for Cu(II) and Cd(II) were found to be 5. These metal ions can be desorbed with
1 M HCl (recovery 95-100 %). The effect of some interfere ions were also
studied. The adsorption process is interpreted in term of Langmuir and
Freundlich equations. The results indicate that with the advantages of high
metal biosorption capacity and satisfactory recovery of Cu(II) and Cd(II).
