Biodegradability and ecotoxicity of amine oxide based surfactants
چکیده انگلیسی

The aerobic and anaerobic biodegradability as well as the aquatic toxicity of two fatty amine oxides and one fatty amido amine oxide were investigated. Aerobic biodegradation was evaluated using the CO2 headspace test (ISO 14593) and biodegradation under anaerobic conditions was assessed employing a standardised batch test. The three amine oxide based surfactants tested were readily biodegradable under aerobic conditions but only the alkyl amido amine oxide was found to be easily biodegradable under anaerobic conditions. Toxicity to Photobacterium phosphoreum and Daphnia magna was evaluated. Bacteria (EC50 from 0.11 to 11 mg l−1) proved to be more sensitive to the toxic effects of the amine oxide based surfactants than crustacea (IC50 from 6.8 to 45 mg l−1). The fatty amido amine oxide showed the lowest aquatic toxicity.
