Synthesis Of Melamine-Formaldehyde Microcapsules Containing Polyfluorene For Fluorescent Detection Of Picric Acid In Aqueous Medium
BULLETIN OF THE KOREAN CHEMICAL SOCIETY(2021)
摘要
To detect nitroaromatic picric acid (PA) in water, polyfluorene (PF) encapsulated melamine-formaldehyde microcapsules (PF@MFMs) were fabricated via in situ polymerizations. Because of the microcapsule structure, PF@MFMs were uniformly dispersed in water maintaining the blue fluorescence of PF in the capsules. The fluorescence intensity of PF@MFMs linearly decreased with increase in the PA concentrations with high limit of detection of 3.0 x 10(-6) M. The addition of other nitroaromatic derivatives, which had structure similar to PA, or various ions did not affect the fluorescence of PF@MFMs, showing high specificity of the microcapsules toward PA.
