Although ultrafiltration (UF) membranes are applicable in wastewater and water treatment, most UF membranes are hydrophobic and susceptible to severe fouling by natural organic matter. In this work, polysulfone (PSf) membrane was blended with silicaluminophosphate (SAPO) nanoparticles, SAPO-34, to study

Ultrapure water produced by a water purification system is one of the most essential and widely used reagents in laboratories. However, its quality is usually the least well-characterized and often overlooked. Here we investigate the contamination of ultrapure water by

The quality of life in patients undergoing hemodialysis is significantly disturbed. There are data that hemodiafiltration (HDF) may be more effective than conventional hemodialysis in the removal of uremic toxins and may reduce frequency and severity of intradialytic and postdialysis

A novel amperometric bienzymatic biosensor has been developed based on the incorporation of Lactate Oxidase (LOx) and Horseradish Peroxidase (HRP) into a carbon nanotube/polysulfone membrane by the phase inversion technique onto screen-printed electrodes (SPEs). In order to improve the sensitivity

Much progress has been made in the biocompatibility of hemodialysis membranes with the development of synthetic membranes. However, despite better biocompatibility, thrombocytopenia has been observed in patients who are dialyzed with various polysulfone membranes. Recent publications have attributed this phenomenon
