International Conference on Environmental Research and Technology (ICERT 2008)Decolorization of Reactive Dye Wastewater using H2O2/pyridine/Cu (II) SystemCL Lim, M Norhashimah*, TT Teng, and I NorliEnvironmental Technology Division, School of Industrial Technology, Universiti Sains Malaysia, 11800 Minden, Penang, Malaysia*Corresponding Phone: +604 653 2236, Fax: +604 657 3678Email: yABSTRACTThe treatment efficiency of the H2O2/pyridine/Cu (II) system on a reactive dye, Cibacron Red FN-R wastewater with a concentration of 1 g/L has been studied using a standard jar test The treatment efficiency was found to be pH A low initial H2O2 concentration of 07 M gave the highest percentage of decolorization of 40% Presence of pyridine markedly increased the treatment efficiency from 75% to 53% with the change in pyridine concentration from 00 M to 01 M Further increase in pyridine concentration of above 02 M caused a decline of 1% - 5% in the percentage color Cu (II) acted as a catalyst and contributed significantly on the treatment An increase in Cu (II) concentration from 0 M to 01 M enhanced the color removal percentage from 08% to 94% A 31% color removal was achieved at an initial concentration of 07 M H2O2, 02 M pyridine and 016 M Cu (II)Keywords: Cibacron red FN-R, decolorization, H2O2/pyridine/Cu (II)这是英文的网址长了点，是PDF格式_website/Proceeding/ICERT%2008%20PROCEEDINGS-Part%202/11-cleaner%20technology,%20control,%20treatment%20and%20remediation%20technique/pdfOriginal ResearchThe Modified Fenton Process for Decolorizationof Dye WastewaterK Barbusiński*Institute of Water and Wastewater Engineering, Silesian University of Technology,Konarskiego 18, 44-101 Gliwice, PolandReceived: 14 November, 2003Accepted: 10 December, 2004AbstractA novel modified Fenton process using heterogeneous catalyst (swarf) was developed to catalyze the oxidation reaction of azo dye Acid Red It was found that swarf could be used to replace iron salts as a catalyst for the Fenton The examined continuous Fenton process proved to be very efficient for decolorization of simulated wastewater containing 100 mg/dm3 Acid Red Performance of the Fenton reactor and regeneration method of the catalyst was The simplified mechanism of hydroxyl radical production in the presence of swarf as a catalyst also was Keywords: Fenton reagent, swarf, azo dye, Acid Red 18第二篇PDF-pdf第三篇第四篇中文PDF旋转填料床中臭氧化处理染料废水的试验第五篇PDFPhotocatalytic Degradation of Textile DyeingWastewater Using Titanium Dioxide and Zinc OxideABBAS J ATTIA, SALIH H KADHIM and FALAH H HUSSEIN*Chemistry Dept, College of Science, Babylon University, Iraqabohasan_Received 23 July 2007; Accepted 22 September 2007Abstract: Photodegradation of a real textile dyeing wastewater taken fromHilla textile factory in Babylon Governorate, Iraq have been Photocatalytic degradation was carried out over suspensions of titaniumdioxide or zinc oxide under ultraviolet Photodegradationpercentage was followed spectrophometrically by the measurements ofabsorbance at max equal to 380 The rate of photodegradation increasedlinearly with time of irradiation when titanium dioxide or zinc oxide was A maximum color removal of 96% was achieved after irradiation time of 5hours when titanium dioxide used at 303K and 82% color reduction wasobserved when zinc oxide used for the same period and at the The effect of temperature on the efficiency of photodegradationof dyestuff was also The activation energy of photodegradation wascalculated and found to be equal to 21 ± 1 kJ mol-1 on titanium dioxide and24 ± 1 kJ mol-1 on zinc Keywords: Photocatalytic degradation, Titanium dioxide, Zinc oxide, UV light, Wastewater treatment,Textile industry-in/open/vol5/no2/0544-219-pdf太多了，不用了吧?
