Abstract
Biodegradability improvement of tetracycline-contg. solns. after an electrochem. pre-treatment was examd. Cyclic voltammetry with a nickel electrode revealed a significant electrochem. activity of tetracycline, in both oxidn. and redn. Electrochem. treatment was therefore performed in a home-made flow cell using a nickel-modified graphite felt electrode as the working electrode. Optimal conditions, namely 100 mg l-1 initial tetracycline, above 0.45 V potential, and between 1 and 6 mL min-1 flow rate, led to a more than 99% conversion yield of tetracycline in oxidn. in alk. conditions, after only a single pass through the percolation cell. However, total org. carbon (TOC) analyses revealed a low mineralization level, i.e., always below 31%, underscoring the importance of a combined electrochem. and biol. treatment. This was confirmed by the favorable trends of the COD/TOC ratio, decreasing from 2.7 to 1.9, and the av. oxidn. state, increasing from 0.044 to 1.15, before and after oxidn. pretreatment at 0.7 V and 3 mL min-1 flow rate. Electrolyzed solns. appeared biodegradable, since BOD5/COD increased from 0 to 0.46 for untreated and pretreated TC at 0.7 V/SCE. Biol. treatment showed only biosorption for non-pretreated tetracycline, while after 11.5 days of culture, the mineralization of solns. electrolyzed in oxidn. was 54%, leading to a 69% overall TOC decrease during the combined process.

Cyclic voltammetry with a nickel electrode revealed a significant electrochem. activity of tetracycline, in both oxidn. and redn. Electrochem. treatment was therefore performed in a home-made flow cell using a nickel-modified graphite felt electrode as the working electrode. Optimal conditions, namely 100 mg l-1 initial tetracycline, above 0.45 V potential, and between 1 and 6 mL min-1 flow rate, led to a more than 99% conversion yield of tetracycline in oxidn. in alk. conditions, after only a single pass through the percolation cell. However, total org. carbon (TOC) analyses revealed a low mineralization level, i.e., always below 31%, underscoring the importance of a combined electrochem. and biol. treatment. This was confirmed by the favorable trends of the COD/TOC ratio, decreasing from 2.7 to 1.9, and the av. oxidn. state, increasing from 0.044 to 1.15, before and after oxidn. pretreatment at 0.7 V and 3 mL min-1 flow rate. Electrolyzed solns. appeared biodegradable, since BOD5/COD increased from 0 to 0.46 for untreated and pretreated TC at 0.7 V/SCE. Biol. treatment showed only biosorption for non-pretreated tetracycline, while after 11.5 days of culture, the mineralization of solns. electrolyzed in oxidn. was 54%, leading to a 69% overall TOC decrease during the combined process.</div></front></TEI><affiliations><list><country><li>Algérie</li><li>France</li></country><region><li>Région Bretagne</li></region><settlement><li>Rennes</li></settlement><orgName><li>Université de Rennes 1</li><li>Université européenne de Bretagne</li></orgName></list><tree><country name="France"><region name="Région Bretagne"><name sortKey="Belkheiri, Daouia" sort="Belkheiri, Daouia" uniqKey="Belkheiri D" first="Daouia" last="Belkheiri">Daouia Belkheiri</name></region><name sortKey="Amrane, Abdeltif" sort="Amrane, Abdeltif" uniqKey="Amrane A" first="Abdeltif" last="Amrane">Abdeltif Amrane</name><name sortKey="Floner, Didier" sort="Floner, Didier" uniqKey="Floner D" first="Didier" last="Floner">Didier Floner</name><name sortKey="Fourcade, Florence" sort="Fourcade, Florence" uniqKey="Fourcade F" first="Florence" last="Fourcade">Florence Fourcade</name><name sortKey="Geneste, Florence" sort="Geneste, Florence" uniqKey="Geneste F" first="Florence" last="Geneste">Florence Geneste</name></country><country name="Algérie"><noRegion><name sortKey="Ait Amar, Hamid" sort="Ait Amar, Hamid" uniqKey="Ait Amar H" first="Hamid" last="Aït-Amar">Hamid Aït-Amar</name></noRegion></country></tree></affiliations></record>Pour manipuler ce document sous Unix (Dilib)
