Triphase Catalysis Based on Gemini Surfactant

The Gemini surfactant can attach to either one or two negative clay surface charges along the same surface, it can act as a bridge between two surfaces, or only one of the two charges need be Due to the heterogeneous charge density distribution in natural MMT, a combination of the aforementioned conformations is likely ( Figure 2 ).

Experimental Study of Surfactant Retention on Kaolinite

We measured equilibrium surfactant retention on kaolinite clay for a large array of surfactants. We demonstrate that the mass balance measurements we used are a rapid way to screen surfactants in terms of their potential to be used in enhanced oil recovery Get price

Surfactant

That is, the filtration of fluid across the capillary wall into the interstitium depends on the hydrostatic pressure gradient and the osmotic pressure gradient across the capillary wall. In the absence of surfactant, to expand the alveoli, the transpulmonary pressure will have to be increased to -28 cm H2O, and this would lead to a net pressure gradient acting outwards. Get price

Particle aggregation

Particle agglomeration can be a reversible or irreversible process. Particle agglomerates defined as hard agglomerates are more difficult to redisperse to the initial single particles. In the course of agglomeration, the agglomerates will grow in size, and as a consequence they may settle to the bottom of the container, which is referred to Get price

Surfactant removal from water solutions by means of

The aim of the study was to compare the removal efficiency of anionic surfactant (belonging to alkylbenzenesulfonate family) from water solutions by means of ultrafiltration and ion-exchange. During the first stage of the experiments, the influence of surfactant type and its concentration, membrane cut-off and polymer material on ultrafiltration performance was evaluated. Get price

2013/11/5We previously developed a novel method to fully exfoliate montmorillonite clay to generate the most fundamental units of nanoscale silicate platelet (NSP). We further modified NSP by capping with various surfactants and found that the surfactant-modified NSP (NSQ) was less cytotoxic. Get price

Advances in Application of Natural Clay and Its

It was shown that coating clay particles with chitosan shifts the net surface charge of clay from negative to positive and the point of zero charge (PZC) of clay from 2.8 and 5.8. The net surface charge of biosorbent particles decreases with an increase in the tungsten concentration of feed water, because the positively charged sites are consumed by the adsorption of tungsten anions.
