A novel water-soluble nano-additive incorporated to PPSU membrane for textile dye removal

In order to develop a polyphenylsulfone (PPSU) membrane for the removal of textile dyes, a novel water-soluble known as partly cross-linked nanoparticles graft copolymer (PCLNPG) is presented in this study as a pore forming agent. In order to fully investigate its effects on properties of the membrane surface, the morphology, and the porosity, and performance, the PCLNPG concentration in the PPSU solution was changed. The results showed that the novel membrane's hydrophilicity and porosity enhanced when it was made using a 0.75 wt.% PCLNPG. To investigate the impact of PCLNPG nanoparticles on the characterization of the novel nanocomposite, a variety of testing methods were utilized. Additionally, longer finger-like pores and a more porous structure were created when the PCLNPG content increased. However, the highest values of water flux and Congo red (CR) dye rejection was 147.05 L ∙ m⁻² ∙ h⁻¹ and 98.59%, respectively. According to results, treating textile wastewater with PPSU/PCLNPG membranes could be a beneficial choice due to its performance features.
