ENVIRONMENTAL
HAZARDS
•
Water and air pollution amongst major environmental issues.
•
Environmental issues need to be addressed in the immediate
future in order to maintain ecological balance
•
Growing dye industries, pharma industries cause major
water pollution.
•
In many areas, water is contaminated with toxic materials
as well as heavy metals.
•
To develop a new, economic and fast acting method to
control water pollution is the need of the day.
ROLE
OF ACTIVATED CARBON IN CONTROLLING
WATER POLLUTION
•
Water pollution is an important environmental issue which
needs immediate attention from chemists.
•
Prepared carbon from various agricultural waste can play a
valuable role in controlling water pollution.
•
Carbon can reduce harmful materials and pollutants from
water thereby minimizing water pollution.
PREPARATION OF CARBON
•
Huge amount of agricultural waste produced in India every
year.
•
It becomes essential to use this waste material for various
important applications in environmental chemistry
•
various types of carbons having different properties can be
prepared from agricultural wastes.
•
Prepared carbons are excellent adsorbants
•
Can be used for water purification, minimizing air
pollution and also as solid supports in many important
environment friendly organic reactions
METHODS OF PREPARATION AND
PROPERTIES OF CARBON
•
Many methods available for preparation carbons
from agricultural waste.
•
Commonly used methods are treating the waste
with sulfuric acid/nitric acid, and then heating
in a furnace at around 600-700 oC.
•
Characterization can be done using advanced
techniques such as TG-DTA, FT-IR, powder XRD.
•
Heating may be carried out in presence or
absence of air which alters the adsorption
properties of the carbon prepared.
•
Adsorption capacity depends upon the mesh size
and the functional groups present on the carbon.
APPLICATIONS
•Prepared
•
carbons act as excellent adsorbants.
They found tremendous applications in water purification.
the prepared carbon find excellent applications for dye
removal from water.
•
•
Find applications in heavy metal removal
•
can be used to purify polluted air.
•Can
from water.
be used as an excellent solid support in carrying out
environment friendly organic reactions.
ADVANTAGES
•
Easy to prepare and handle
•
Do not require tedious methods and sophisticated techniques
for characterization.
•
agricultural waste is available in large amounts and hence
preparation cost is negligible.
•
Various carbons having different functional groups on the
surface can be used for various applications.
•
Can be stored under normal conditions.
•
Easily recyclable of the carbon with high reproducibility of
the results.
PRESENT
WORK
•
Collection of agricultural waste from near Pune, MS, India.
•
Crushing of the waste material to form a powder.
•
The powder will be subjected to acid treatment and then
heated.
•
The carbon will be prepared as per the reported procedures.
•
The prepared carbons will be characterized using the
appropriate analytical methods.
•
The prepared carbons will be used for various applications
depicted above.
•
Contd……
PRESENT
WORK
•
The first stage will consist of collection of the
agricultural waste which will then be dried thoroughly.
•
In the next stage, carbons will be prepared from the dried
material using the reported procedures.
•
In the third stage, the prepared carbons will be tested for
their dye removal activity. Using mathematical models like
Frieundlich Isotherm described for adsorption activity, the
adsorption capacity of the carbons will be determined.
•
In the fourth and last stage of the project, data
compilation will be done and results /conclusions will be
drawn from the available data. The results may provide
economic, fast acting and environmentally benign solutions
for ecologically important water pollution hazards.
