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.
https://www.yrdcarbon.com/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=480After 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 initialconcentr
