Chromophoric groups

WebDuring the photocatalytic process, FCTM-20 exhibited the best adsorption and degradation of MB solution. This is because the chromophoric groups of MO and MB lead to different energy requirements for FCTM-20 in the degradation process. WebCompounds suitable for UV detection contain a chromophoric group, such as an aromatic ring, two conjugated double bonds, carbonyl group and others. If you are uncertain if all compounds are in your mixture are UV active, it might be a good idea to combine UV detection with another detector, such as an evaporative light scattering detector (ELSD).
