Description

Traitement des dversements d'hydrocarbures l'aide d'un adsorbant naturel base de polythylne et de luffa by Mostafa Hamdy Estimated delivery 3-12 business days Format Paperback Condition Brand New Description Les travaux expérimentaux menés dans le cadre de cette étude montrent que le polyuréthane de synthèse naturelle et les déchets végétaux de luffa pourraient être utilisés à l'échelle commerciale pour l'adsorption d'hydrocarbures à la surface de l'eau de mer. Dans cette procédure, de nombreux facteurs ont été étudiés qui influent sur la capacité d'adsorption des hydrocarbures (grammes d'hydrocarbures/grammes d'adsorbant) du polyuréthane et du luffa lorsqu'ils sont utilisés comme adsorbants dans le nettoyage des marées noires. Ces facteurs sont les suivants: type d'eau, poids de l'adsorbant, temps d'agitation, volume d'huile, température, hydrophobicité de l'eau - oléophilie de l'adsorbant, pH et réutilisabilité des adsorbants. L'efficacité de l'élimination de l'huile a été étudiée à l'aide d'eau de mer et d'eau du robinet. L'efficacité de l'élimination de l'huile et la capacité d'adsorption étaient plus élevées avec l'eau de mer qu'avec l'eau du robinet. Le poids des adsorbants de 0,2 gramme de polyuréthane et 0,5 gramme de luffa correspond à la quantité optimale d'huile adsorbée et à la quantité acceptable d'eau absorbée avec tous les types d'huiles utilisées. Ils ont donc été utilisés dans les expériences. L'augmentation du temps d'agitation augmente l'efficacité de l'élimination de l'huile de l'eau de mer.

  1. Seller sent me the wrong book, but the book they sent sounded interesting enough for me to keep it. I still contacted the seller and communication was fast and professional. They apologized for sending me the wrong book and said I could return it for a refund. I told them that I liked the book they sent me and wanted to keep it. They were happy. Told them thank you and happy new year. People make mistakes, but the fact that this seller was quick and professional and apologized made a difference.

  2. The basket is perfectly what I ordered and as listed. It came in the factory packaging and was perfect upon delivery. Thank you postal service lol. The delivery took way longer than listed though, it was listed to come in a week from purchase, but took a whole month. I had some concerns at first, but communication with the company was top notch and they were very professional and answered most of my questions satisfyingly. Just prepare for a longer wait than listed, but I got what I bought lol.

  3. The two new out-of-print books I ordered were exactly as described and shipped promptly. I did ask the seller's support person (an AI chatbot, I think) to be sure to package the items carefully, and "he" said that he'd make that request of the shipping department. I knew this was hooey, and as I expected, the books were shipped in nothing but a padded paper mailer, no other protection. I got lucky, no damage, but don't bother making special requests of this seller.
