J. Cent. South Univ. Technol. (2008) 15(s1): 443-446 DOI: 10.1007/s11771-008-396-x Viscoelasticity of mixed polyacrylamide solution XU Li-na(徐丽娜) (PetroChina Daqing Oilfield Engineering Co. Ltd, Daqing 163712, China) Abstract: The viscoelastic behavior of polyacrylamide solution is crucial for its application in various industries. The mixed polyacrylamide solution was prepared by mixing......
through flotation tests, solution chemistry calculations, zeta potential measurements and infrared spectroscopic analysis. The results show that fine ilmenite shows good floatability in pH range of 4?10... and molecular association of a high surface activity component in sodium oleate solution becomes higher and keeps the floatability good. Key words: ilmenite; sodium oleate; solution chemistry......
