Adsorption of dye from wastewater by using mesoporous silica Arghavan Mirahsani Arghavan67@yahoo com Date of Submission 8 27 2012 Department of Civil Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Dr Hasty Hashemi nejad Dr Alireza BadieiAbstractSBA 15 nanoporous silica was prepared and functionalized with mono amino sites groups via post synthesisgrafting method to develop efficient adsorbents of dyes in wastewater The prepared materials have beencharacterized by XRD SEM N2 adsorption desorption and FTIR Adsorption of a cationic dye malachite green on functionalized SBA 15 was investigated under variousconditions of pH 5 6 and 7 temperature 10 20 and 30 C dosage of adsorbents 0 1 0 3 and 0 5 g l anddye concentration 50 100 and 150 mg l Maximum amount of equilibrium adsorption capacity to achievemaximum removal percentage R 100 in optimum conditions concentration of dye in solution 100mg L pH 7 dosage of adsorbent 0 3 g L was estimated 333 mg g The adsorption performances of thematerials were optimized by using Taguchi method and then isotherm kinetic and thermodynamic propertieswere analyzed at optimum condition The results showed that the overall process was fast and the kinetic waswell fitted by pseudo second order kinetic model The obtained experimental data were well agreed withLangmuir model Therefore the maximum amount of monolayer dye adsorbed can be predicted as 650 mg g This study shows that the silica based nanoporous organic inorganic hybrid material is promising sorbent for theremoval of malachite green from aquatic solutions Key WordsSBA 15 dye adsorption Malachite green
