Fund Project:

A linear copolymer of methyl acrylate and N-vinylcarbazole was prepared in ben-zene using AIBN as an initiator and then hydrolyzed in NaOH aqueous solution.The fluores-cence intensities of the aqueous solution of the hydrolyzed water soluble copolymer increasewith the increase of the pH value and the concentration of the cationic surfactant.Mercuryions (Hg²⁺) showed a certain quenching effect on the fluorescene of the copolymer aqueoussolution.The concentration of Hg²⁺ is in a linear relationship with the fluorescence intensity (logI₀/I) of the polymer solution,that may be used to determine the trace amount of mer-cury by fluorescence quenching method.
