Polyetherimide Membrane with Polyoxometalates

Check if the same lab product or an alternative is used in the 5 most similar protocols
A commercially available polymer, polyetherimide (PEI, Ultem ® 1000, General Electric Plastics), was selected as the polymeric material for membrane fabrication, where a sol-gel precursor, aluminum-tri-sec-butoxide (ASB, Sigma-Aldrich), was used as the additive. Nmethyl-2-pyrrolidone (NMP, >99.5%, Merck) was used as a solvent for dope preparation.
Polyethylene glycol (PEG, Sigma-Aldrich) was used as a pore-former during the membrane fabrication. (3-aminopropyl)trimethoxysilane (APTMS, Sigma-Aldrich) was used as a coupling agent for POMs incorporation with the membrane. H5[PV2Mo10O40] (PVMo) was selected as a model of POMs and synthesized according to the literature [32] . Reactive black 5 (RB5, Sigma-Aldrich) was selected as a model dye. OXONE ® (monopersulfate compound, 2KHSO5•KHSO4•K2SO4, Sigma-Aldrich) was used as an oxidant for catalytic degradation.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
