Modified Mesoporous Silicate MCM-41 for Zinc Ion Adsorption: Synthesis, Characterization and Its Adsorption Behavior
Modified MCM-41 has been prepared by bi-functionalization of thiol and amino functional groups onto mesoporous silicate MCM-41. Elemental analysis (EA), thermogravimetry analysis (TGA) and FTIR techniques were used to quantify the attachment of the thiol and amino functional groups to the mesoporous silicate pore wall.Powder X-ray diffraction (PXRD) and nitrogen adsorption techniques were used to establish the pore diameter,packing of the pores and specific surface area of the modified mesoporous silicate MCM-41. Adsorption behavior for 18 metal ions on this sorbent has been studied and discussed. This sorbent has high affinity for zinc ions against amino- or thiol-functionalized MCM-41 sorbents.
