| Abstract | ||||
| Toxic gases, such as ammonium are unsafe materials that harm safety and environmental risks. Even though many sensors have been stated for the detection of ammonium, a superficial, rapid, cost-effective sensor is still sought-after in the field. Here we establish a superficial and rapid method to synthesize a fluorescent metal–organic framework for the highly selective and sensitive detection of ammonium. Zirconium phthalic diamine framework (Zr-PH-Diamine) is synthesized. The synthesized material shows visible color changes upon exposure to ammonium from pink to yellow. In addition, fluorescence is show under UV illumination when the Zr-PH-Diamine is exposed to ammonium. The Zr-PH-Diamine coated paper sensors show the highest fluorescence enhancing at an emission wavelength of 565 nm with ammonium concentration as low as 1 ppm. Consequently, the proposed plan not only offers a fast and convenient protocol for selective detection of ammonium but also offers great potential in practical applications, especially for industry and area whom manufacture of nitric acid or hair dyes, keep public safety and decreasing environmental pollution. | ||||
