Abstract

Select a mesoporous material MCM-41, macroporous materials MOSF as an adsorbent, studied the adsorption experiment of simulated wastewater containing uranium.  Investigated the effect of adsorption time, temperature, pH, MCM-41 dosage, initial concentration uranyl on adsorption rate. Investigated the initial concentration, the reaction time on the MOSF adsorption of uranyl solution; and at the same pH, reaction time, temperature, dosage, initial concentration. Compared MCM-41 with MOSF on the adsorption of uranyl solution; draw Langmuir adsorption isotherms and Freundlish adsorption isotherms of adsorption isotherm laws, and analyzed consisting of MCM-41 by XRD spectra, used extraction methods for MOSF pretreatment. Experimental results show that: adsorption equilibrium time is 50min for radiation wastewater on MCM-41 , the adsorption process the Langmuir adsorption isotherm law; equilibration time is 50min for MOSF adsorption of radioactive waste , the adsorption process meets Freundlish adsorption isotherm law; under the same conditions , the adsorption efficiency of MOSF is greater than the adsorption efficiency of MCM-41.
