Description
The effect of a natural, biodegradable surfactant obtained using a nov-el and efficient chemical reaction between cysteine (a thiol-based amino acid) and an octanoyl (C8) compound, was investigated for its application to the ion flotation removal of low levels of different contaminant ions from aqueous solution. The syn-thesised amino acid-based single-chain surfactant shows a high water solubility and exhibits extensive foaming in a...[Show more]

dc.description.abstract | The effect of a natural, biodegradable surfactant obtained using a nov-el and efficient chemical reaction between cysteine (a thiol-based amino acid) and an octanoyl (C8) compound, was investigated for its application to the ion flotation removal of low levels of different contaminant ions from aqueous solution. The syn-thesised amino acid-based single-chain surfactant shows a high water solubility and exhibits extensive foaming in a typical flotation chamber over a wide pH range. In a batch ion flotation process, this surfactant was able to remove 97‒99% of the 5ppm of strontium, lanthanum, arsenic and different heavy metal ion levels present in contami-nated water, in a simple, single-stage physiochemical process. Also, significant differ-ences in ion binding selectivities could be used as the basis for the complete separa-tion of some specific ions from mixed solutions, using the ion flotation process. Recy-cled water is an invaluable resource but it often also contains inorganic and organic nutrients, and chemical and biological substances, such as enteric microbial pathogens, which are often not monitored. This is a key inhibition to its reuse. The application of a novel CO2 bubble column sterilization process is presented here and compared with other commonly used processes. | |
