PREPARASI DAN KARAKTERISASI TITANIUM DIOKSIDA (TiO2) MESOPORI SEBAGAI ADSORBEN LOGAM Cu(II) DAN METHYLENE BLUE

Abstract

Titanium dioxide (TiO2) is a mesoporous materials having pore size diameter 2-50 nm, pore structure uniform,
large surface area, and uniform of pore size distribution. The purpose of this research is to synthesize TiO2 mesoporous
materials using hydrothermal method, titanium tetra isopropoxide (TTIP) as a precursor and pluronik 123 (P123) as
surfactant agent for the pore-forming template. The products of TiO2 mesoporous has analyzed using the Brunauer-
Emmet-Teller (BET) methode, FTIR, XRD and DSC. The results of these analyses of surface area and pore size
distribution were 121 m2/g, pore volume 0.173 cc/g and pore diameter of 9.46 nm. The results of XRD analysis show the
tetragonal structure and anatase phase. TiO2 mesoporous was generated the amount of Cu(II) adsorption were 450 mg/g
for 60 minutes and the amount of methylene blue adsorption were 96 mg/g for 60 minutes.
