  • Are multi walled CNTs effective for surfactant removal?
  • Multi walled CNTs (MWCNTs) were used because of the relatively lower cost. The results show high removal efficiencies for certain surfactants. The paper provides a promising scientific foundation for the application of MWCNTs to surfactant removal but there are issues.
  • Can biosurfactants replace chemical surfactants?
  • Hence, there exists a great feasibility of production of biosurfactants on large scale as a replacement for the chemical surfactants . Supply of external supplements such as nutrients and other materials for improving the production yield would also result in the higher production cost.
  • What is the primary surfactant used for a long time?
  • Introduction Soap is the primary surfactant used for a long time . Saponification is a process in which a long-chain carboxylic acid from body fats of animal origin or nonedible oil from vegetative sources is refluxed with sodium or potassium hydroxide to synthesize the surfactants at the onset.
  • What is a biosurfactant derived from Candida tropicalis?
  • The biosurfactant, produced from Candida tropicalis with molasses, frying oil, and cornsteep liquor in distilled water as the growth medium. 30–80% of zinc, and copper removal is achievable within 30 mins of serial washing in the column .
