dc.description.abstract The aim of this study is the capture of pharmaceutical pollutants from water usingcovalent organic framework (COF) and activated carbon (ACP) as adsorbents. It presents as well the first report on pharmaceutical removal from water by COF. This study is preceded by an investingation about pharmaceutical products in algeria compared to data from the world with determination of the largely used pharmaceuticals in algeria that may contaminate the aquatic environment. the adsorption tests were carried out in batch experiments. The results showed that COF are more efficient in capturing pharmaceutical products than ACP. COF showed short times to reach equilibrium varying between 10 minutesand 1 hour, much less than the 3 hours obtained by ACP. Various models have been applied to the kinetic study and the adsorption of the selected molecules on the COFs and CAP after highlighting the effect of certain paramenters such as concentration and pH. Lipophilic ibuprofen has shown a high adsorption capacity onto COF compared to acetaminophen and ampicillin. This capacity is reached a value of 133 m- equivalent of 90% at neutral pH and temperature of 21°C in ultrapure water. Ibuprofen has also shown a good adsporption onto ACP compared to phenobarbital. Analyzes of pharmaceuticals adsorption by COF in real waters show that ibuprofen has a higher adsorption capacity compared with phenobarbital and acetaminophen and this adsorption capacity is affected by the characteristics of these waters. this study has highlighted the good appeal of FOCs for less polar lipophilic pharmaceuticals in ultrapure waters and in the real waters used to achieve competitive adsorption, which suggest that COFs may be preconceived for selective capture contaminants in the waters. fr_FR
