Abstract:
Zeolite is used mainly as a filtering material for. wastewater treatment and purification
of drinking water. Zeolite is commonly used for the filtering process taking into
consideration its chemical stability, high mechanical strength, more developed specific
surface, porosity and also because it is a cheap and freely available material. The main
objective of the study is to focus on the development and evaluation of a process for
the removal of amino acid from wastewater. The study specifically discusses the
adsorption of isotherms in the liquid phase of various amino acids for furfural. The
study has used chromatographic methods for amino acid determination. It has been
found that sorption of amino acids by natural zeolites and modified analogs are
advantageous. In all likelihood less bulky molecule of alanine is adsorbed better on
zeolites, which enter into the pores or form strong Van der Waals forces around the
pores. The molecules of amino acids cannot penetrate in a cavity of zeolites such as
5 A 0 / as a cavity makes approximately 4-5 A 0 /; but they can form hydrogen bonds with
amino-acid's molecule. Moreover, there exists two or more types of acidic hydrogen
atoms in amino acid. This is one of the possibilities to have a harder bonding with the
zeolite's surface hydroxyl groups. The method presents the perspective technology of
the purification of water (treatment of wastewater). This work focuses on the
development and evaluation of a process for the removal of amino acids from waste
water; it precisely discusses the adsorption of isotherms in liquid phase of various
amino acids for furfural. The proposed method can also be used for amino acid
determination by liquid chromatographic methods with the zeolitic columns.
