Adsorption Performance of a Novel Complex Absorbent to Phosphorus in Aqueous Solution

Abstract:

In the paper, a new composite absorbent was prepared by diatomite and zeolite. The structure of the prepared composite absorbent was characterized by Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), Scanning electron micrograph (SEM) and Energy dispersive spectrometer (EDS). In addition, the kinetics and thermodynamics properties of the new composite absorbent to the phosphate in aqueous solution were investigated as well. The results showed that, new crystalline phases and fresh bonds might be formed in the prepared composite absorbent. The metallic contents in materials interacted with diatomite, leading to the formation of inorganic polymerized silicon complex and the increasing of the element content of calcium, magnesium, aluminum and ferrum in the new composite absorbent. It was found that the pseudo-second-order equation could fit the adsorption kinetics well, and the adsorption isotherms could be qualified by the Langmuir equation.
