Data for: Biosynthesized magnetite-perovskite (XFe2O4-BiFeO3) interfaces for toxic trace metal removal from aqueous solution
Description
The adsorption behaviors and maximum adsorption capacity (qmax) were described via Langmuir [35] and Freundlich [36] adsorption isotherms, being recorded by a fiber-based fluorescence spectrometer (PL; USB 4000, Ocean Optics, USA). The data were analyzed by origin8.0 software. Therein, the Langmuir mode can take place onto a surface containing a finite number of identical sites, as well as the monolayer adsorption behavior. The Freundlich mode can be applied to the multilayer adsorption on heterogeneous interfaces. The corresponding adsorption isotherms were estimated using the following equations: Langmuir isotherm: ; Freundlich isotherm: . Where qe, Ce, qmax, b, kF and n reflect the trace metal ion capacity, the equilibrium concentration (mmol·L-1), the max adsorption capacity (mmol·g-1), and the adsorption intensity of Langmuir coefficient (L·mmol-1), the Freundlich coefficient (mmol·g-1) and the adsorption strength (L·mmol-1), respectively. The b, n, R2 data has been listed in the two table below. The qmax data has been used for the drawing of Figure 11. The Data of adsorption isotherms form Shewanella oneidensis MR-1 synthesized XFe2O4-BiFeO3 in the table I. The Data of adsorption isotherms form Shewanella putrefaciens CN32 synthesized XFe2O4-BiFeO3 in the table II .
