In the present paper, the adsorption of Astrazon Black AFDL dye onto Vietnamese diatomite has been demonstrated.
The diatomite was characterized by XRD, SEM, TEM, EDS, and nitrogen adsorption/desorption isotherms.
The results show that diatomite mainly constituted centric type frustules characterized by pores as discs or as cylindrical shapes.
The adsorption kinetics and isotherms of dye onto Vietnam diatomite were investigated.
The experimental data were fitted well to both Freundlich and Langmuir in the initial concentration range of 400–1400 mg L−1.
The average value of maximum adsorption capacity, q m , calculated from Freundlich equation is statistically similar to the average value of maximum monolayer adsorption capacity calculated from Langmuir equation.
The thermodynamic parameters evaluated from the temperature dependent on adsorption isotherms in the range of 303–343 K show that the adsorption process was spontaneous and endothermic.
The Webber and pseudo-first/second-order kinetic models were used to analyze the mechanism of adsorption.
The piecewise linear regression and Akaike’s Information Criterion were used to analyze experimental data.
The results show that the dye adsorption onto diatomite was film diffusion controlled and the goodness of fit of experimental data for kinetics modes was dependent on the initial concentration.
