Synthesis and Properties of the Polymeric Surfactant Based on Maleamic Acid and Styrene杨永清Department of Applied Chemistry, School of Science, Northwestern Polytechnical University摘 要:An alternative polymeric surfactant P(M3/St) was synthesized by solution polymerization of maleamic acid as hydrophilic monomer and styrene as hydrophobic monomer. Some......
and pyrophyllite, by a cationic Gemini surfactant as collector and starch as depressant was investigated as function of reagents concentration and pulp pH. Further studies of artificially mixed minerals... of around 10. Key words: diaspore; bauxite; reverse flotation; Gemini surfactant  ......

CALORIMETRIC STUDIES ON THE STRUCTURE OF MICROEMULSION WITH NONIONIC SURFACTANT滕弘霓摘 要:<正> Enthalpic studies on the state of water in hex-adecane/hexanol/ AEO8/water system have been conducted. The results show that water exists in three states such as bound water,trap water and free water. The enthalpic effect of condition that water to oil ratio......
Accelerating leaching of copper ore with surfactant and the analysis of reaction kineticsChun-ming Ai1,2,Ping-ping Sun1,Ai-xiang Wu2,Xun Chen2,Chao Liu31. College of Safety Science and Engineering...:To solve the problem of low permeability and lower extraction rates of high-mud ores, a surfactant was added as a penetrant to the pregnant leaching......
Effect of Surfactant Stabilizers on the Distribution of Carbon Nanotubes in Aqueous MediaYury N Tolchkov,Zoya A Mikhaleva,R D A Sldozian,Nariman R Memetov,Alexey G Tkachev摘 要:The results of a study on the homogeneity of suspensions are described considering the effect of different types of surfactant stabilizers and their concentrations on the uniform......
Trans. Nonferrous Met. Soc. China 22(2012) 3147-3155 Effect of surfactant Tween-80 on sulfur oxidation and expression of sulfur metabolism relevant genes of Acidithiobacillus ferrooxidans PENG An-an1... of Ministry of Education of China, Central South University, Changsha 410083, China Received 30 July 2012; accepted 21 November 2012 Abstract: The effects of surfactant Tween-80 on the growth, sulfur oxidation......
. A complex alkali resistant phosphate surfactant with good permeability was prepared. The wettability of surfactants was investigated by measuring the immersion time, sinking time and capillary effects..., the complex system exhibits better wettability in 5.0-7.0 mol/L of NaOH solutions, in comparison with either corresponding single surfactant component employed, and wettability is well correlative......
The Role of Surfactant and Costabilizer in Controlling Size of Nanocapsules Containing TEGDMA in Miniemulsion郭进新1,黄翠21. School and Hospital of Stomatology,Wuhan University2. Key Laboratory of Oral... and polyurethane as wall material used for self-healing bonding resin were prepared by interfacial polycondensation in miniemulsion. The influence of surfactant and costabilizer concentration on nanocapsules size......
) of the quaternary ammonium surfactant [cetytrimethyl ammonium bromide(CTMAB),cetyl pyridine bromide(CPB),benzyl dimethyl dodecyl ammonium chloride(BDMDAC),and dodecyl trimethyl ammonium chloride(DTMAC)].The surfactant could react with Au(CN)2-to form the ionic complex,and the compound could be extracted by SPE column of reversed-phase bonded silica gel.Hence,a new method of SPE was proposed......
