In order to control the pollution by anionic surfactants in seawater, a simple, accurate and sensitive reverse flow injection (rFIA) spectrophotometric method for the determination of anionic surfacta...
Concentrated dispersions consisting of 310 nm poly(styrene–ethylacrylate) nanospheres and ethylene glycol, which exhibited pronounced shearthickening behavior, were prepared in this work. The influen...
Dispersants, usually blending with several surfactants and a solvent, are used to enhance oil spill dispersion as small droplets in water column. Although there is growing acceptance of dispersants as...
This paper describes recent levels of surfactants measured in a coastal lagoon ecosystem highly stressed by human activites: the Orbetello lagoon (Southern Tuscany, Italy, Ramsar Site IT008). Signific...
Biomass burning contributes to various organic substances in the atmosphere. Levoglucosan has been recognised as one of the indicators of biomass burning and surfactants are a group of molecules whic...
Mesoporous materials have attracted a great deal of attention because of their controllable structures and compositions, which make them suitable for a wide range of applications in catalysis, enviro...
The binding behaviour of 1.4-diamine anthraquinone derivative disulphonic CI Acid Blue 80 dye with nonionic surfactants based on ethoxylated alkylamines and fatty alcohols or alkylphenol (NPE) in aque...
以非离子表面活性剂为乳化剂,对生物油和柴油混合制备乳化油技术进行了研究。以乳化油稳定性为评价指标,研究了乳化剂的选择,并考察了HLB值、乳化温度、乳化时间对乳化油稳定性的影响。试验结果表明:在乳化温度为30~50℃的条件下,以2%的司班80和吐温80复配液并辅以0.1%的正辛醇构成的HLB值为8的乳化剂乳化含有5%生物油和柴油的混合液,可以形成油包水(W/O)型乳化油,其稳定时间可达60h;显微镜...
This contribution/study deals with partial hydrophobisation of O-(carboxymethyl)starches (CMS, DS = 0.1 and 0.3) with alkylamine (C6, C10, and C12). The reaction was performed in methanol and dimethyl...
The mechanism of decomposition of non-ionic surfactants, Triton X-n type, under the influence of ionising radiation is described. The survey of the available data strongly suggests that OH radicals ar...
The effect of the use of the triblock copolymer Pluronic P123[(PEO)20(PPO)70(PEO)20, Aldrich] and the non-ionic polyoxyethylene-lauryl ether Brij 35 as surfactants on the textural, structural and el...
Anhydrous milk fat was emulsified with s1-CN (casein), s2-CN, ß-CN, -CN, -lactalbumin, ß-lactoglobulin, Tween 80, or phosphatidylcholine to produce a 30% fat cream in a 0.1 M imidazole pH ...
期刊信息 篇名 On-line ion pair solid-phase extraction of electrokinetic multicommutation for determination of trace anion surfactants in pond water 语种 英文 撰写或编译 撰写 作者 Hu Y Y,He Y Z*,Qian L L,Wang L 第一作者单位 De...
Factors affecting the interfacial rheology of films of food proteins and surfactants at air-water and oil-water interfaces are reviewed. A distinction is made between interfacial shear rheology and in...
