Abstract :
Guava (Psidium guajava, white Indian) is common
fruit bearing plant found throughout the Indian
peninsula. It is said to be native to Mexico and Southern
America and now can be found in many of the Asian
countries. It is grown in tropical and sub-tropical region
around the world. Guava leaves have shown many
properties like antibacterial, bioadsorbent, etc. The
bioadsorbent property can be exploited to remove
coloured residues from water bodies. Problems like
water pollution have arisen due to rapid
industrialization and urbanization. Various harmful
dyes like Coomassie brilliant blue, used in both textile
industries and laboratories, are expelled into water
bodies. To reduce the effects of such dye on ecology the
research was carried out using guava leaves as
bioadsorbent. That being the case the Coomassie
brilliant blue solution at different pH was treated with
guava leaf powder and the decrease in absorbance was
noted at 625 nm.
The Guava leaves were obtained from Mumbai
suburban. The leaves were dried and powdered for
further testing as bioadsorbent. All the chemicals have
been used were of analytical grade.
The study showed high absorption rate in acidic
medium as the colour changed from dark blue to light
blue. The optimum pH for bio-adsorption was found to
be 3. As the amount of guava leaf powder increased, the
rate of adsorption also increased.
Guava leaf powder is effective as a bioadsorption
as rate of adsorption increases with increase in guava
leaf powder. With further optimization it can become
potential source of adsorbent.
