Examination of produced water from the Al-Hamada oilfield, Libya.
… chemicals quaternary ammonium compounds (quats) were detected with alkyl chain lengths of C12 (m/z 304), C14 (m/z 332), C16 (m/z 360) and C18 (m/z 388). On the whole, knowledge is needed about the level of oilfield chemicals in the produced water and groundwater and also phenol and alkyl …

Structural and kinetic studies of surfactant and phospholipid monolayers at the air/liquid interface using sum-frequency generation spectroscopy
In this work, the non-linear optical technique of sum-frequency spectroscopy (SFG) has been used to investigate a variety of surfactant and phospholipid systems at different interfaces. Firstly, the effects of temperature and ionic strength on the adsorption of cationic and non-ionic surfactants …
