Chromium Ions]]>KumaranM.D. Bala PrasathkumarM. KumarD.J. Mukesh KalaichelvanP.T. 7201367The heavy metal contamination of the water bodies is a worldwide environmental
problem and its removal is a great challenge. This long term environmental hazard
has received considerable attention in recent years. The use of low cost waste
materials as adsorbents of heavy metal provides an eco friendly complimentary
solution in removal of the dissolved metal ions and utilization of the waste
materials. In the present investigation, biosorption of Cr (VI) ions was carried
out using Aspergillus terreus dead biomass and the effect of various
parameters such as pH, temperature, incubation time, initial metal concentration
and initial biomass concentration which influenced the removal of Cr (VI) ions
was studied. The experimental results showed that Aspergillus terreus
is an effective biosorbent for the removal Cr (VI) ions. There was a strong
influence of pH over biosorption process; especially over pH 1 it reached 54%.
Similarly bisorption was observed higher when there was increase in the biomass
concentration and decrease in initial metal concentration. Temperature also
has a considerable impact on biosorption process, maximum at 27°C. Further,
the untreated and treated biosorbent were characterized by FTIR spectral analyses
and SEM micrograph to study the nature of bisorbent before and after the removal
of Cr (IV) ions. The results of the present study revealed the potential use
of Aspergillus terreus biomass as biosorbent for the removal of Cr (VI)
from the aqueous environment.]]>Ahalya, N., R.D. Kanamadi and T.V. Ramachandra,2005Cicer arientinum).]]>8258264Aksu, Z., T. Kutsal, S. Gun, N. Haciosmanoglu and M.
