  • Solution Property Investigation of Combination Flooding ...

    2019-12-12 · The aim of this work was to investigate the solution properties of a new polymer–surfactant (SP) flooding system, including hydrophobically associating polyacrylamide (HAPAM) and mixed surfactant [mixture of fatty acid disulfonate anionic gemini surfactant (DMES) and non-ionic surfactant Triton X-100 (TX-100)]. The critical micelle concentrations (cmc’s) of …

  • A kinetic investigation of cationic starch adsorption and ...

    Abstract The flocculation kinetics of kaolin particles suspended in 0.01 mol/L NaCl solution and adsorption properties of cationic starch on kaolin surface have been investigated at pH 5.0. Adsorption kinetics of cationic starch followed pseudo-second-order model (R2 > 0.98). Flocculation kinetics showed that increase in flocculant dosage resulted in higher rate constants …

  • Preparation of starch-g-polyacrylamide and its utilization ...

    Starch- based adhesives are capable of wetting polar surfaces such as cellulose, penetrating pores, and forming strong bonds through mechanical and physical bonds. This paper studies the modification of starch by grafting with acrylamide, and the relation between m
