**Applications of Surfactants**

species, isolated from municipal sewage and industrial wastewater, in removing of anionic surfactants from environment as well as their potential application in biotechnology. The application of several electrochemical techniques, such as cyclic voltammetry, chronoamper‐ ometry, chronocoulometry, and selective electrodes for studying the behavior of surfactants in solution as well as at the interfaces, has been discussed by Dr. Schulz in Chapter 9. The last chapter of the book is devoted to explain the use of SAXS and SANS techniques as pow‐

Finally, I would like to express my gratitude to Ms. Martina Usljebrka, the publishing proc‐ ess manager, and InTech Open Access Publisher for their efforts in the publishing process. I would also like to thank my family and families of all other collaborators for their patience and acceptance of the lost evenings. I wish that this book can give an insight into the field.
