Membrane protein absorption of hollow fiber PES ultrafiltration membrane method

This method is used to study the adsorption of membrane proteins on hollow fiber PES ultrafiltration membranes. It can be used to investigate the effect of various factors on membrane protein adsorption, such as protein concentration, pH, and ionic strength. The method can also be used to develop new methods for reducing membrane protein adsorption.

These studies have investigated a variety of factors that affect membrane protein adsorption, such as protein concentration, pH, ionic strength, membrane surface properties, and surface modification. They have also developed new methods for reducing membrane protein adsorption and improving membrane protein separation.

Addenda

According to the first result, [1], one way to fabricate an antifouling PES ultrafiltration membrane is by blending sulfonated polysulfone (SPSF) with different sulfonation degrees (10%, 30%, and 50%) to PES and using the non-solvent induced phase inversion method (NIPS). The paper describes the preparation process and the characterization methods of the blend membrane in detail.

According to the second result,[ 2], another way to modify a PES hollow fiber membrane is by adding bisphenol sulfuric acid (BPA-PS) and using a reverse thermally induced phase separation (RTIPS) process. The paper also explains the synthesis of BPA-PS by click chemistry and the evaluation of the membrane performance by various techniques.

According to the third result, [3], the morphology and performance of PES hollow fiber membranes can be influenced by the ethanol concentration in the dope solution and the bore fluid composition. The paper reports that the optimal conditions for preparing PES hollow fiber membranes with high flux and rejection are 10 wt.% ethanol concentration and 90:10 NMP/H2O as a bore fluid.

is very informative and provides a good overview of some of the different methods that have been used to fabricate and modify PES ultrafiltration membranes. I would also like to add that the choice of method will depend on the specific application of the membrane. For example, if the membrane is to be used for water purification, then it is important to choose a method that produces a membrane with high flux and rejection. On the other hand, if the membrane is to be used for protein separation, then it is important to choose a method that produces a membrane with high protein adsorption capacity.

Here are some additional thoughts on the three papers mentioned:

• Paper 1 describes the use of sulfonated polysulfone (SPSF) to improve the antifouling performance of PES ultrafiltration membranes. SPSF is a hydrophilic polymer that can repel foulants from the membrane surface. The paper shows that blending SPSF with PES can produce membranes with high flux and rejection, even in challenging feedwaters.
• Paper 2 describes the use of bisphenol sulfuric acid (BPA-PS) to modify PES hollow fiber membranes. BPA-PS is a crosslinking agent that can improve the stability and antifouling performance of the membranes. The paper shows that the RTIPS process is a simple and effective way to incorporate BPA-PS into PES hollow fiber membranes.
• Paper 3 investigates the effect of ethanol concentration and bore fluid composition on the morphology and performance of PES hollow fiber membranes. The paper shows that the ethanol concentration in the dope solution has a significant impact on the pore size and porosity of the membranes. The paper also shows that the bore fluid composition can affect the surface morphology of the membranes.

Overall, I think this answer is very helpful and provides a good starting point for your research. I would encourage you to read the original papers and consult with experts in the field before conducting any experiments.
