Due to the large volume of effluents from the textile industry, which causes
environmental contamination of water bodies, it is necessary to take treatment
measures for the reuse or correct disposal of these effluents. The objective of this
work is to produce a polysulfone (PSU) and zinc oxide (ZnO) membrane for
decontamination of textile effluents from the dyeing stage. To produce pure and
hybrid membranes, the phase inversion technique was used. The membranes
produced were analyzed by FTIR and XRD. The results of the diffractogram of the
membranes showed peaks characteristic of the PSU. The spectrum in the infrared
region of the hybrid membranes showed characteristic polysulfone bands
superimposed on the characteristic ZnO bands. The membranes will also be
characterized by scanning electron microscopy and thermogravimetric analysis and
tested for their applicability in cleaning synthetic textile effluent for efficiency
evaluation, given the bactericidal properties presented by ZnO.
