Optimal dissolution and viscoelastic behavior of polyamide-66 in formic acid for membrane fabrication

High-performance polymeric membrane technology is rapidly developing worldwide with the introduction of new materials and processes. Considerable research efforts are being made to establish a polymer that can be used for ultrafiltration (UF) or nanofiltration (NF) applications. The development modified polyamide-66 its compatibility in wastewater essential elements quest advances improvements technology. optimized conditions synthesis critical making it commercially viable. Response Surface Methodology (RSM) was find optimum dissolution formic acid. A model developed validated experimental data, showed good agreement R2 0.9984. condition minimizing viscosity determined. For minimum (3.64 cp), temperature wt.% were 20 ?C 0.6, respectively.
