This work aims at determining the desired membrane preparation conditions for polyethersulfone (PES) composite membrane for the ultrafiltration of synthetic oil in water emulsion. 3-aminopropyltriethoxysilane modified silica (APTES-SiO₂) nanoparticles were prepared via one-pot stober method and blended in PES dope solutions which significantly influenced membrane properties. The effects of PES, polyethylene glycol (PEG), APTES-SiO₂ and coagulation bath temperature (CBT) on the oil permeate flux (OPF), oil rejection (OR) and pure water flux (PWF), as well as their interactions were investigated. Response surface methodology based on the central composite design were used for statistical analysis, optimization and modeling of the PES membrane. The significant terms that affects PWF was observed to be PES, PEG and the interacting effects between PES and APTES-SiO₂ whereas, PES and PEG were observed for OPF. In the case of OR, the significant terms were observed to be the quadratic effects of PES, APTES-SiO₂, coagulation bath temperature as well as the interactions between PES and PEG. The optimum conditions for PES, CBT, APTES-SiO₂ and PEG were found to be 17.25 wt.%, 15 °C, 3.6 wt.% and 3.72 wt.%, respectively with PWF, OPF and OR maintained at 235.2 kg/m² h, 159.8 kg/m² h and 99.2%, respectively.

这项工作旨在确定聚醚砜（PES）复合膜在合成油包水乳液超滤中所需的膜制备条件。通过一锅法（stopot）方法制备了3-氨基丙基三乙氧基硅烷改性的二氧化硅（APTES-SiO ₂）纳米颗粒，并将其掺入显着影响膜性能的PES涂料溶液中。PES，聚乙二醇（PEG），APTES-SiO _2的作用考察了混凝浴温度（CBT）对油渗透通量（OPF），排油率（OR）和纯水通量（PWF）的影响，以及它们之间的相互作用。基于中央复合设计的响应面方法用于PES膜的统计分析，优化和建模。观察到影响PWF的重要术语是PES，PEG，以及PES和APTES-SiO ₂之间的相互作用，而观察到PES和PEG对于OPF。在OR的情况下，观察到的重要术语是PES，APTES-SiO ₂的二次效应，凝固浴温度以及PES和PEG之间的相互作用。PES，CBT，APTES-SiO ₂的最佳条件发现PWF，OPF和OR分别为17.25 wt。％，15°C，3.6 wt。％和3.72 wt。％，而PWF，OPF和OR分别维持在235.2 kg / m ² h，159.8 kg / m ² h和99.2％ ， 分别。
