ABSTRACT: Environmental sustainability apart from spoken at different levels needs to investigate the management of industrial
activities in terms of eco-friendliness.
It is well known that effluents from various industries become a major source
of environmental degradation in particular water pollution. Thus water analysis
report turns to be more significant, to determine the quality and standard of
life maintained in a typical ecosystem. This study includes the analysis of
physico-chemical factors of raw as well as treated water samples from Korattur
Lake employing nano sized adsorbents like titania with tuned structural and
morphological properties through organic plant extract. The XRD analysis, BET
analysis, DRS-UV analysis, SEM and TEM analysis have been carried out and
reported. The marked influence of leaf extract as a template is reflected in
reduced crystallite size (12.4 nm) with maximum surface area 105 m2/g
along with bathochromic shift of absorption edge. The usual indicators of
contamination level at a given source namely Biological Oxygen Demand
(BOD-85%), Chemical Oxygen Demand (COD-94.5%), Dissolved Oxygen (88%), Total
Suspended Solids (TSS-75.6%), Electrical Conductivity (74.5%), Chloride (89%),
Nitrate and Phosphate contents etc. were used to ascertain the efficiency of
contaminants removal using tea leaf extract mediated nano titania. The
reliability factor of the treatment process was found to be less than 1,
revealed the effectiveness and reliability of nano material.
