Application of Porphyrin Modified SBA-15 in Adsorption of Lead Ions from Aqueous Media

Mesoporous silica SBA-15 was synthesized using P123 as surfactant and functionalized with (3-chloropropyl) triethoxysilane. For the first time, the composite of THPP-SBA-15 was prepared using incorporation of tetrakis(4-hydroxyphenyl)porphyrin in functionalized SBA-15. The materials were characterized by BET, SEM, XRD, FT-IR, DRS, and UV–Vis spectroscopy… CONTINUE READING
