Composite Membranes on the Basis of New Nanomaterials in the Class MCM-41 Modified with Metals and SAPO Applied in Wastewater Purification

Abstract:

Composite membranes have been prepared by VCo-MCM-41, Mn-MCM-41, Co-MCM-41 and Co-SAPO dispersion into a PSF solution, by phase inversion method. Inorganic nanomaterials were synthesized by hydrothermal treatment. The microporous structure of the composite membrane was quatitatively investigated by scanning electronic microscopy SEM and quantitatively through determining minimum, maximum and mean pore size and also the surface density of pores. Permeation and catalytic properties of the composite membranes were tested for purification of the waste water. Composition of the waste water after permeation through membranes shows a good separation and activity for sulfides (reduction degree of over 93,7%). Keywords: composite membrane, nanomaterials, VCo-MCM-41, Mn-MCM-41, Co-MCM-41, Co-SAPO, waste water
