Posted by The antidepressant carbamazepine (CBZ) is one of the most frequently detected chemical compounds in urban water [1].
Water insoluble cyclodextrin polymers and also titanium dioxide incorporated polymers were tested for the removal of CBZ from water. Several physicochemical parameters were assessed such as pH, temperature, salts, etc.
The results show that the adsorption process occurs within 20 minutes and it is not affected significantly by pH or salts. To induce the degradation of CBZ, titanium dioxide incorporated polymers were also prepared. By irradiating the material with UV light successful photodegradation was achieved. This technique could be an effective way for CBZ removal, not to mention, that the system can be reused -after desorption with methanol- at least five times [2] .
