Study On The Adsorption And Degradation Of Ionic Dyes And Their Applications

Chapter 1:This chapter provides an overview of the development of dye. Outline the classification and application of dye, the methods of dye wastewater treatment and progress of the study. Introduction to the research development and application situation of dye ink.Chapter 2:With methylene blue (MB), basic fuchsin (BF) and Crystal Violet (CV) for the model of cationic dyes, this chapter studies and compares the adsorption effect of the graphene and graphete oxide. The effects of pH, temperature, time on the experiment results were investigated, and the optimum experiment conditions was determined. The result shows that graphete oxide had higher adsorption capacities to cationic dyes,and the adsorption capacities is the highest in neutral conditions of adsorption at low temperature. With the advantages of simple and easily-obtained adsorption conditon to cations and their large surface area, graphete oxide can also be used to remove organic and heavy metal ions, and it is likely to be more widely in its applications in water treatment.Chapter 3:This chapter choose reactive red 3BSN, reactive black B-ED, reactive blue BET for anionic dye-model, study the decolorization effect of reduction method to anionic dye, and mainly resaerch the experimental pH, temperature, time influence on degradation. Studies shows that the best degradation pH is 10, and the decolorization rate up to 90%.Chapter 4:Reactive red 3BSN reactive black B-ED, reactive blue BET were used as bonding agent for water-based dye ink research. Basic performance of the 3 color inks were tested and this chapter also studied of reductive formamidine sulflnic acid stability. Results show that 3 color inks are available in -30℃-40℃ within normal use, draw lines are longer than the 60 m/g,warranty period is longer than 6 months,and the stability of formamidine sulfinic acid can be increased significantly by 1% acetic acid.Chapter 5:The chapter is the summary to the experiments, and also describes the future development prospects of the graphete oxide and graphene adsorption for waste-water treatment, the application range of degradable water-based anionic dyes and FAS.
