摘要

This paper is a study on how mass fraction of ammonium salt solution, soaking liquid ratio and regeneration temperature affect the quality of clay materials reformed from porous materials which are modified by ammonium salt solution, and their effect on adsorption and regeneration of benzene. The study shows that when the mass fraction of the ammonium salt solution reaches 0.2%, solid-liquid ratio is 3g: 20mL, and regeneration temperature is 100 °C, the adsorption properties of modified clay is best for absorbing benzene. The analysis of SEM photographs of clay shows that after being modified, the surface of the porous material becomes smooth, large pores disappear, and more moderate holes and micropores come into being. As a result, its ability to capture benzene and lower the content of basic groups have been greatly improved. Hence its ability to absorb benzene have been greatly improved. The study proves that: modified porous materials can play a better role in physical and chemical adsorption as the modification is conducive to keep the dynamic balance and optimizes the adsorption of benzene.
