Structural properties of activated carbon

When the radon adsorption coefficient of activated carbon is constant,n is proportional to the concentration of radon. In this case, Equation (10) represents the functional relationship among the total number of activated carbon V, radon concentration and adsorption (or exposure) time. Therefore, the concentration of radon in the environment can be calculated according to the total number of activated carbon and adsorption time.Simulation calculation and result analysis of total number of activated carbon According to Equations (5) and (10), a computer program can be written to calculate the relationship between the total number of Y in the process of radon adsorption on activated carbon and the relationship between the total number of Y after the removal of activated carbon and the change of time.
In order to verify the accuracy of the simulation calculation, two 12g activated carbon bags thickness of activated carbon ~ 1.5cm) were put into the container containing uranium ore, and then taken out after radon adsorption for 30 min and 85 min. After continuous measurement, the change curve of total Y number of activated carbon over time could be obtained.
According to the adsorption duration used in the experiment and the appropriate value of n (in the calculation process, when the adsorption duration is 30 min, n=480;activated charcoal powder wholesale uk
When the adsorption time is 85 min, take n-600), and the calculated theoretical curve is shown in FigureIt can be seen from the figure that the measured curve is in good agreement with the theoretical curve.Fig. 2 is the simulation result of the total number of Y taken out over time after activated carbon adsorbs 1 radon atom from the environment every second and continues to adsorb for 3 days.After the activated carbon was taken out, the total number of V reached the maximum after t time, and then the total number became smaller. After about 50 min, the total number of V decreased by a negative exponential function.After adsorption equilibrium was achieved in the adsorption capacity remained at 3.6 mg lL above, grapefruit peel activated carbon adsorption of ammonia followed pseudo second order kineticmodel of the process; by the Henry equation and Freundlich equation with correlation coefficient R'known, Henry isotherm models and Freundlich isotherm models can be used for the des Cription ofgrapefruit peel on the ammonia adsorption characteristics of activated carbon; ammonia initialconcentration,dosage, pH and temperature on the ammonia adsorption are affected, litle effect oftemperature on adsorption.yrd activated charcoal
