For the analysis of anionic surfactants, the addition of an anionic IN absorbing compound to the buffer was investigated to achieve indirect detection of the non-absorbing surfactants.

Abstract:
A unique penetration instrument has been developed to evaluate the role of surfactants in kraft pulping process. This instrument can screen surfactants which can improve the wood impregnation more effectively and much faster than pilot-plant experiment. The role of surfactants in wood penetration has been explored. Surfactants can improve wood impregnation by dispersing the extractives in the wood structure and optimizing the interfacial properties between wood surface and kraft liquor. The addition of two blends of anionic and nonionic surfactants into kraft pulping process results in a signi

The objective of this investigation was to observe and evaluate the effects of surfactants on the biodegradation of toluene in the subsurface. Soil microcosms containing gasoline were used to simulate conditions of an aquifer contaminated with hydrocarbons. The surfactants were the nonionics, Surfonic N-40 and N-95. Three volumes of gasoline, 0.005, 0.05, and 0.1 mL, were injected into separate microcosms in order to observe changes in toluene concentration in both adsorbed component conditions and free-phase, interstitial gasoline conditions.

Abstract:
Gas hydrates are a topic of great interest and intense investigation. Traditionally, these compounds have been seen as a nuisance to the oil and gas industry, which can plug pipelines and cause hours of costly downtime. More recently, gas hydrates have been viewed as a possible energy source due to the vast amount of methane trapped in the form of gas hydrate. Many researchers have also proposed the possibility of transporting natural gas in the form of gas hydrate may be safer and more economical than using liquid or compressed natural gas. Gas hydrate may also offer the possibility of reduci
