Description
Summary:A low-cost isoniazid-based scavenger resin was previously prepared and successfully used to capture aldehydes and ketones in solution by using a batch approach. The present work compares batch and continuous processes in relation to the preparation of the scavenger resin and the effectiveness of cyclohexanone scavenging. The batch preparation of the resin proved to be the better choice because the resin produced in the continuous flow suffered deformation on its surface that prevented access to the active sites in the internal porous polymer matrix. Conversely, the continuous-flow approach presented higher capturing yields than the batch. The optimized scavenging process was successfully used to remove formaldehyde present in a solution and the carbonyl compounds present in an ethanolic extract of Cymbopogon citratus.
