Biosorption capacity was found dependent mainly on dye and adsorbent dosage. Highest adsorption efficiency was achieved with fungal biomass at 0.5g/l. Dye concentration (100 mg/ l) was found optimum for maximum dye removal. At acidic pH (3-5) and 30 C, Methyl Orange biosorption increased significantly in first 6 h. </smarttagtype></smarttagtype> <br/> <br/>Page(s): 1075-1077 Sat, 28 Nov 2009 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/6742 Title: Influence of pH, temperature and cultural media on decolorization of synthetic dyes through spent substrate of different mushrooms <br/> <br/>Authors: Ahlawat, O.P.; Singh, Rajender <br/> <br/>Abstract: Spent substrate of <i>Agaricus bisporus</i>, <i>Pleurotus sajor-caju </i>and <i>Lentinula edodes </i>was evaluated for decolorization of 4 different dyes under different cultural conditions (media, incubation temperature and medium pH). Potato dextrose broth media supported highest decolorization (90% of Rhodamine B and Methyl Violet 2B, 93% of Chicago Sky Blue 6B and 88% of Quinaldine Red) after 3 days of incubation with <i>P. sajor-caju </i>spent substrate. Optimum pH requirements were 7.0 and 10.0 for Rhodamine B and Methyl Violet 2B with spent substrate of <i>L. edodes</i>, while 4.0 and 7.0 with <i>A. bisporus </i>and <i>P. sajor-caju.</i> However, for Chicago Sky Blue 6B and Quinaldine Red, it was 4.0 and 7.0 for spent substrates of all 3 mushrooms. Spent substrate of <i>A. bisporus </i>supported highest decolorization of Rhodamine B (93-95%) and Methyl Violet 2B (91-100%), followed by <i>L. edodes </i>+ <i>P. sajor-caju</i>. Temperatures of 25 and 35^oC were most effective for decolorization of Rhodamine B (90%) and Methyl Violet 2B (97%) with spent substrate of <i>A. bisporus </i>alone. In case of Chicago Sky Blue 6B and Quinaldine Red, temperature requirement for decolorization was same but with spent substrate of <i>L. edodes</i>, <i>P. sajor-caju </i>and <i>L. edodes </i>+ <i>A.</i> <i>bisporus </i>for Chicago Sky Blue 6B, and <i>A. bisporus</i>, <i>P. sajor-caju </i>and <i>L.edodes </i>+ <i>A. bisporus </i>for Quinaldine Red. <br/> <br/>Page(s): 1068-1074 Sat, 28 Nov 2009 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/6741 Title: A study on degradation of pesticide wastewater by TIO₂ photocatalysis <br/> <br/>Authors: Rajeswari, R; Kanmani, S <br/> <br/>Abstract: Photocatalytic degradation of Carbendazim, a commercial grade pesticide, has been investigated. Optimum degradation (76%) of Carbendazim (40 mg/l) was observed in 60 min at pH 6 and catalyst concentration (1g/l). Degradation was lowered by the presence of carbonate and phosphate ions. Studies on real industrial wastewater revealed that removal of pesticide (99%) was faster and mineralization (76%) required longer duration. Formation of inorganic ions (ammonium and nitrate) proved fragmentation of pesticide and formation of intermediates. <br/> <br/>Page(s): 1063-1067 Sat, 28 Nov 2009 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/6740 Title: Energy efficient and environmentally sound technologies for small and medium scale textile cluster <br/> <br/>Authors: Velavan, R; Rudramoorthy, R; Balachandran, S <br/> <br/>Abstract: <smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="country-region"><smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="City"><smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place"> Continuous and sustained growth of small and medium scale units in Indian textile garment sector has resulted in increased CO₂ emission and effluent discharge. Analysis of processing units in Tirupur, India, has helped to identify some energy efficient and environmentally sound technology (E3ST) measures. This paper identifies potential for pollution reduction with selected E3STs. </smarttagtype></smarttagtype></smarttagtype> <br/> <br/>Page(s): 1058-1062 Sat, 28 Nov 2009 22:58:59 GMT
