Biotemplate Assisted Nano Titania and Its Environmental Performance

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.
