gratitude goes to my supervisor Dr Hoang Thi Tuyet Nhung for her unreserved assistance towards the completion of this work We express our thanks to Dr Nguyen My Linh – Head of environment technology department, for her unrelenting support and help We also say thank for the encouragement, guidance from the teachers and staff of FHQ, FCFT and from the seniors and our friends We would also like to thank to all environmental technologically teachers who have taught and helped us in four years of college Last but not least, We express our gratitude to our parents for their support and encouragement throughout our study Ho Chi Minh, 29 / / 2019 Nguyen Hoang Thuy Tien an Dao Thanh Long ABSTRACT The "Efficiencies of color removal using TiO2 – chitosan beads and films" project aims to create a low- cost and new eco-friendly material to remove colors in aqueous solution In this study, methyl orange, near wash yellow, acid blue and textile color specifically used There are eight different kinds of materials were prepared: bare chitosan (C0) bead/film, Chitosan –TiO2 (CTi) bead/film, Chitosan – Gly (CG) bead/film, Chitosan – Gly – TiO2 (CGTi) bead/film The materials were analyzed of chemical composition, structure, surface area of materials by modern physico-chemical analysis methods such as X-ray powder diffraction analysis (XRD), scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy analysis (EDX) and Fourier transform infrared spectroscopy (FTIR) analysis C0 bead, CG beads have the same low ability to remove colors and COD, only12 – 15% due to the adsorption capability of Chitosan The decoloration efficiency of CTi beads are about 30 – 35% The highest decoloration efficiencie is of CGTi beads which are from70 to 75% The optimal kind of material in bead form, HRT, mass and pH are CGTi10, 90 minutes, g, pH = with AB and NWYand pH = with MO, respectively The results show that CTi film has fewer treatment efficiencies than CGTi10 film and higher treatment efficiencies than C0 and CG The treatment efficiencies of CGTi film is slightly higher compared with that of CGTi bead, due to the dispersion of TiO2 on the surface of the CGTi material which helps the photocatalytic catalytic process perform better The optimal kind of material in film form, HRT and pH are CGTi15, 30 minutes, pH = and 5, respectively Keywords: Glycerol, Chitosan, Tripolyphosphate, Crosslink, Decoloration, TiO2, … an COMMITMENT Our name are Nguyen Hoang Thuy Tien and Dao Thanh Long, are students of K15 specialized Environmental Engineering Technology, student IDs: 15150038 and 15150018, respectively We assure that this thesis is a scientific research of ourselves, completed under the guidance of Dr Hoang Thi Tuyet Nhung The information references in this topic are collected from reliable, proven, widely publicized sources, and we cited it clearly in the Reference The research results in this thesis were completed with our seriousness, honesty and guaranteed not overlapping with other topics We would like to take the honor and prestige of ourselves to ensure this assurance Ho Chi Minh, 29 / / 2019 Nguyen Hoang Thuy Tien an Dao Thanh Long CONCLUSION Page 68 an Conclusion - C0 beads and CG beads have the same ability to remove colors and COD, only 12 – 15% due to the adsorption capability of Chitosan The decoloration efficiencies of CTi beads are about 30 – 35% The decoloration efficiencies of CGTi beads are about 70 - 75% - The order of the factors affecting on the photocatalytic process with CGTi beads is: TiO2 concentration, hydraulic retention time (HRT), initial color concentration (C0), the mass of bead (m) and pH - The optimal beads, HRT, m and pH were CGTi10, 90 minutes, 2g, pH = with AB and NWY and pH = with MO, respectively The optimal initial concentration (C0) of MO, NYW and AB were of C0 = mg/L, C0 = 80 mg/L and C0 = mg/L, respectively For continuous – flow reactor (UVA light) with CGTi10 beads, decoloration efficiencies increased rapidly after 10 minutes (60 – 70%) and reached equilibrium after 20 minutes (70 – 80%) The reactor with a diameter of 30 mm always shown the highest effective Treatment efficiencies of CTi film were less than those of CGTi10 film and higher than those of C0 and CG - The treatment efficiencies of CGTi film slightly higher treatment efficiencies than CGTi beads due to the dispersion of TiO2 on the surface of the CGTi films which helps the photocatalytic catalytic process work better - The order of the factors affecting the photocatalytic process with CGTi films is: TiO2 concentration, hydraulic retention time (HRT), initial color concentration (C0) and pH - The optimal film, HRT and pH were CGTi15, 30 minutes, pH = and 5, respectively The optimal initial concentration (C0) of MO, NYW and AB were of C0 = mg/L, C0 = 80 mg/L and C0 = mg/L, respectively At the same conditions, decoloration efficiencies and COD removal of CGTi film are much higher than CGTi beads Recommendation - Observe the photocatalytic activity of CGTi with different kinds of organic color or textile color - Batch and continuous-flow reactor with UVA light using CGTi film for color and COD removal Page 69 an - Use the CGTi beads and film to treat actual wastewater and calculate the cost when putting into use Page 70 an REFERENCES VIETNAMESE DOCUMENTS [1] Le Vu Tuan
