Pesticides removal from water using modified piperazine-based nanofiltration (NF) membranes
This study attempted to explore the removal of two pesticides (atrazine and diazinon) from water by synthesized thin-film composite (TFC) polyamide nanofiltration (NF) membrane. Poly (piperazineamide) NF membranes were prepared by interfacial polymerization technique. In this work, the effects of addition of triethylamine (TEA) as an accelerator in aqueous phase were examined on the performance and morphology of TFC membranes. The morphological studies represented that a rough and dense film was fabricated on the PSf support membrane. The NF membranes performance was evaluated with 0.03 g/l atrazine and diazinon dissolved in distillated water as feed solution, separately. The modified membranes with TEA exhibited higher rejection and water flux compared to the other membranes. Moreover, in all experiments, diazinon was better rejected than atrazine. It was observed that the water permeability and diazinon rejection increased from 22 l/m2/h and 95.2% for the unmodified membrane to about 41.56 l/m2/h and 98.8% for the 2% (w/v) TEA modified membrane. This indicated a significant improvement in the performance of poly (piperazineamide) TFC NF membranes for pesticides removal.
