Description

In this research, with the aim of engineering arrangement of nanoparticles within membrane pores, ZrO₂ nanoparticles was modified by sulfate and carboxylate functional groups. Thereafter, the filtration performance of PSf/ZrO₂, PSf/Zr-COOH, and PSf/Zr-SO₄ nanocomposites in treating textile wastewater were compared. SEM, EDX and AFM analysis showed that the functional groups manipulate surface and structural properties of the membranes. Therefore, water flux of ¹³PSf/^2.68Zr-SO₄ and ¹³PSf/^2.68Zr-COOH were 42% and 32% more than those of ¹³PSf/^2.68ZrO₂. Moreover, dye rejection of ¹³PSf/^2.68Zr-SO₄,¹³PSf/^2.68Zr-COOH and ¹³PSf/^2.68ZrO₂ was about 99% and 97% and 95%, which is 14%, 12% and 10% higher than raw membrane.
