In this dissertation, the metal-organic framework ZIF-8, Carbon quantum dots and these hybrids are CQD @ ZIF-8, the porosity and application of this hybrid have been investigated to measure the amount of mercury ion in water samples. The unique feature of carbon quantum dots, especially the high fluorescence emission, has been to be used in applications such as sensor systems. On the other hand, ZIF-8, due to its high porosity properties, high surface area, structure and uniform cavities, the application is abundant as absorbent. The hybrid of these quantum dots with the ZIF-8 has created a very good sensor system for measuring heavy metals such as mercury in various water samples.
For synthesis of CQD@ZIF-8, the solvent method was used and further centrifuges were used to separate the sediment.
To measure the amount of mercury in different samples of water using CQD @ ZIF-8 and a one-time variable method. The optimum value obtained for the parameters studied: pH=6, the amount of adsorbent is equal to 0.05 g/L, the optimal time is 4 minutes and the detection limit for mercury ions is equal to 0.03 mg/L, It has been reported.
