Abstract: Artificial dyes have been used for more than a hundred years, and there are many kinds of artificial dyes, so the application range is quite wide, such as textile industry, medicine industry, etc. However, artificial dyes are not easily decomposed by microorganisms and some dyes are toxic. Therefore, with the large-scale use of artificial dyes, the wastewater discharged from the factory will cause water environmental pollution if it is not treated. The adsorption method is currently a cheaper and more commonly used method. In order to obtain better adsorption efficiency, researchers have used different kinetic equations to study the adsorption mechanism. The data in this study meets the nonlinear pseudo-second-order kinetic equations. However, the nonlinear equations increase the difficulty of calculation and simulation.
