Abstract

Four kinds of clay minerals (montmorillonite, illite, chlorite, mica) were selected to study the adsorption of tetracycline (TC) in environment and characterized by XRD, FTIR, and SEM. The theory of sites energy distribution was established, which comprised a collection of systems and analytical methods, offering a direct and practical approach to investigating the energy distribution of adsorption sites within adsorption systems. In kinetic analysis, the adsorption of TC conforms to the quasi-second-order kinetics and internal diffusion model, showing that the number of sites has a great influence on the adsorption process. In isothermal study, the generalized Langmuir model better describes adsorption process, indicating the uneven adsorption energy. The site energy distribution theory analyzes the effects of temperature, pH and humic acid on the adsorption of TC, revealing that the change of conditions affects the number of adsorption sites and the average adsorption energy on clay minerals.

期刊介绍： Chemical engineering enables the transformation of natural resources and energy into useful products for society. It draws on and applies natural sciences, mathematics and economics, and has developed fundamental engineering science that underpins the discipline. Chemical Engineering Science (CES) has been publishing papers on the fundamentals of chemical engineering since 1951. CES is the platform where the most significant advances in the discipline have ever since been published. Chemical Engineering Science has accompanied and sustained chemical engineering through its development into the vibrant and broad scientific discipline it is today.
