Abstract Iron-pillared bentonite (FB) was prepared by Fe(III) modified bentonite, and then the composites (FB-OS) were
prepared by iron-pillared bentonite and oyster shell powder. The composites were characterized by FTIR, SEM,
TGA, and EDS, and the phosphorus removal test was carried out. The results showed that FB-OS contained a
large amount of CaO. Its structure was compact, but there were gaps in it. The maximum bending stress and
compressive strength were 43.7 N and 0.927 MPa, respectively. The phosphorus removal test showed that the
phosphorus removal rate of FB-OS was more than 90%, and measured the maximum adsorption capacity was
48.31… More >
