functional hybrid mesoporous MCM-41-PAA was prepared using diatomite as a silicon source
CTAB as a template
and polyacrylic acid as a dopant based on mesoporous materials with a uniform adjustable pore size structure. The composition
structure and morphology of MCM- 41-PAA were characterized by FT-IR
XRD
SEM and nitrogen adsorption and desorption. MCM-41-PAA
as an adsorbent
was used to adsorb mercury ions
and the factors such as the dosage of the adsorbent
the initial Hg(II) ions concentration
the pH value of solution and the adsorption time were explored. The results showed that the adsorption capacity could reach 132mg/g when the dosage of adsorbent
