Abstract

A new ferric silicate adsorbent was prepared by coprecipitation method with iron sulfate and water glass.Through fourier transform infrared spectroscopy (FT-IR),X-ray powder diffractometry (XRD),scanning electron microscopy (SEM),BET,and the adsorption-desorption characterization method,the various physical and chemical properties of the material were tested and analyzed.The effects of adsorption time,adsorbent dosage,temperature and solution pH on the adsorption characteristics of phenol in simulated wastewater were systematically investigated.The results shown that the specific surface area of the adsorbent was as high as 560m2/g and the average pore diameter was 3.5nm.When the initial concentration of phenol in the simulated wastewater was 100mg/L,2g of the adsorbent was added,the adsorption time was 120min,the adsorption temperature was 25℃,and solution pH was 7,the removal rate and the adsorption amount were as high as 74% and 3.7mg/g,respectively.The adsorption isotherm fit was consistent with the Langmuir model,so the adsorption of phenol was monolayer adsorption.
