Researchers from Babol University of Technology Report New Studies and Findings in the Area of Chemical Engineering

May 7, 2014

By a News Reporter-Staff News Editor at Journal of Engineering -- A new study on Chemical Engineering is now available. According to news reporting out of Babol Sar, Iran, by VerticalNews editors, research stated, "Polyethersulfone (PES) ultrafiltration membranes were prepared via phase inversion induced by immersion precipitation with a blending method in different concentrations of two hydrophilic monomers, namely 3,5-diaminobenzoic acid (DBA) and gallic acid (GA). Herein we report the effects of these two monomers as additives in the casting solution on the morphology, performance, and antifouling properties of the membranes."

Our news journalists obtained a quote from the research from the Babol University of Technology, "The membranes were characterized in terms of pure water flux permeation, humic acid (HA) separation, membrane structure, and morphology. Experimental results show that the different component ratios of each monomer affected the structural property of blended membranes and surface roughness. The equilibrium water content (EWC) and water contact angle were measured to evaluate the change of hydrophilicity of the modified membranes. Trends exhibited that those two additives increased the hydrophilicity of the membranes because of their strong hydrophilic groups. The HA removal by the PES membrane increased considerably with the addition of DBA and GA in the casting solution."

According to the news editors, the research concluded: "Moreover, the membranes prepared by adding DBA and GA in the PES casting solution exhibited better antifouling properties."
