Abstract
In this research, a porous organic framework was used to extract and determine the amount of mercury by visible-ultraviolet light. This porous structure was identified using different techniques such as Fourier infrared spectrometer, X-ray normal diffraction spectrum, scanning electron microscope, X-ray energy diffraction spectroscopy, thermal analysis and specific area measurement. Parameters affecting the extraction such as pH of the sample solution, adsorbent amount, detergent volume and absorption time were studied. The detection limit was 1.2 ng/L. Then, under optimal conditions, this method was used to determine the amount of mercury in real samples of city water and well water.
