AB  - Divalent mercury ion (Hg(2+)) is one of the most common pollutants in water with 
      high toxicity and significant bioaccumulation, for which sensitive and selective 
      detection methods are highly necessary to carry out its detection and 
      quantification. Fluorescence detection by organic dyes is a simple and rapid 
      method in pollutant analyses and is limited because of quenching caused by 
      aggregation dye molecules. Hydrotalcite (LDH) is one of the most excellent 
      carrier materials. In this study, an organic dye acridine orange (AO) was 
      successfully loaded on the LDH layers, which significantly inhibited fluorescence 
      quenching of AO. The composite AO/LDH reaches the highest fluorescence intensity 
      when the AO initial concentration is 5 mg/L. With its enhanced fluorescent 
      property, the composite powder was fabricated to fluorescence test papers. The 
      maximal fluorescence intensity was achieved with a pulp to AO/LDH ratio of 1:5 
      which can be used to detect Hg(2+) in water by naked eyes. Hg(2+) in aqueous 
      solution can be detected by instruments in the range of 0.5 to 150 mM. The 
      novelty of this study lies on both the development of a new type of mineral-dye 
      composite material, as well as its practical applications for fast detection.
