Biodegradability of surfactants

The biodegradation of surfactants is studied by means of many different tests and sometimes under different conditions. Some factors with significant influence on the results are uncontrollable factors and in other cases are not controllable. This causes a dispersion in biodegradability data that makes comparisons difficult. For this reason only general conclusions can be obtained from the data available. Swisher carried out an exhaustive collection of available data in his complete study on surfactant biodegradation [385]. Some basic and significant features of biodegradation of alcohol and alcohol ether sulfates are discussed below. [Pg.293]

The second part, comprising four chapters, centers on an extensive set of data regarding the different environmental levels of all analyzed surfactants and their major degradation products in various countries. The aerobic biodegradation of surfactants is treated extensively, with emphasis on metabolic routes and novel and persistent metabolites formed. In addition, anaerobic degradation and sorption is also covered. [Pg.27]

In order to avoid further biodegradation of surfactants after sampling or during storage, various substances have been used for the preservation of samples. So far, mainly formaldehyde and salts of copper(II) and mercury(II) [7,14] have been applied, and formaldehyde has been found to be the most effective of these, although still not sufficient for long term storage. This topic is discussed in more detail in Chapter 4.3. [Pg.425]

The interest in cleavable surfactants has increased rapidly in recent years and the topic has been covered in review papers during the last decade [1-4]. This chapter begins with a relatively thorough discussion about the incentive for hydrolyzable surfactants, continues with a discussion about biodegradation of surfactants, which is important for understanding the concept of hydrolyzable surfactants, and then gives an account of the development of hydrolyzable surfactants with an emphasis on recent results.
