Abstract
This paper is aimed at a further development in the adsorption performance of fly ash on dye wastewater.The study involves modifying fly ash by using sodium carbonate to obtain sodium carbon-ate modified fly ash,obtaining optimal process conditions of treating dye wastewater simulated by orange-yellow Ⅳ by batch adsorption test,meanwhile,conducting several characterizations and analysis inclu-ding scanning electron microscope,infrared analysis,X-ray diffraction analysis and specific surface area test.The results show that under the conditions of temperature by 25℃,initial mass concentration of Or-ange yellow Ⅳ solution by 200 mg/L,pH solution by 2,and dosage of adsorbent by 3 g/L,the adsorp-tion rate of Orange yellow Ⅳ could reach 96.11%.关键词
