Adsorption Kinetics Study three.three. Adsorption Kinetics Study The adsorption kinetics study was performed to to discover the relationship in between the The adsorption kinetics study was performed discover the partnership between the adsorption amount qt and t. As As seen Figure 3, thethe adsorption capacity thethe fly ashadsorption amount qt and t. observed in in Figure 3, adsorption capacity of of fly ash based and slagbased geomaterials onon Cs elevated drastically inside 24 h. To be able to based and slagbased geomaterials Cs increased drastically within 24 h. In order to recognize the adsorption kinetics in far more detail, the mechanism from the adsorption course of action in a lot more detail, the mechanism from the adsorption understand the adsorption kinetics processstudied by fitting fitting the pseudofirstorder Disperse Red 1 Protocol reactions and pseudosecondary was was studied by the pseudofirstorder reactions and pseudosecondary reactions reactionsexperimental data of data study. In order to investigate the consistency between for the for the experimental this of this study. As a way to investigate the consistency among the plus the experimental outcomes beneath the optimized experimentalexperimental the model model and also the experimental benefits under the optimized circumstances, the conditions, the pseudofirstorder and pseudosecondaryused to apply used to apply the of pseudofirstorder and pseudosecondary results had been outcomes have been the linear graphs linear egraphs t and et/qtt) tt towards the Cs t towards the Cs adsorption kinetic model,Figures six and 7, ln(q qt ) of ln(q q and t/qt adsorption kinetic model, as shown in as shown in Figures six and Table three shows the linear constants (Rlinear constants parameters from the two respectively. 7, respectively. Table 3 shows the two ) along with the other (R2) plus the other parameters of theof Cs adsorption to geomaterials calculated from Figures 6 and 7. from kinetic models two kinetic models of Cs adsorption to geomaterials calculated For the Figures six adsorption the cesium the slagbased geomaterials, the pseudofirstorder model cesium and 7. For kinetics of adsorption kinetics on the slagbased geomaterials, the pseudofirstorder worth than that in the two worth than that of the pseudosecondorder includes a greater R2 model features a greater Rpseudosecondorder model, indicating that the model, indicating that the adsorption procedure was primarily physical adsorption. On the adsorption process was mainly physical adsorption. Alternatively, the Cs adsorption other hand, the fly ashbased geomaterials isthegoodashbased geomaterials is in great Cs adsorption kinetics of in fly agreement with the pseudosecondary kinetics of agreement with indicates that chemical adsorption was much more dominant.
