摘要: Abstract In this study, xanthan gum (XA) was used as a hydrophilic biopolymer additive for the modification of polyethersulfone (PES) membrane to removal humic acid (HA). The membranes are prepared using phase inversion technique and concentration XA varied from 0.5 1.5 wt%. characterized function hydrophilicity, equilibrium water content (EWC), porosity studies functional group analysis. Membrane surface cross-sectional morphology studied scanning electron microscope. lower contact angle value 64.2° exhibited, when 1.5 wt% incorporated in PES ensures that increase hydrophilicity pristine membrane. Further, higher permeability (PWP) 68.9 −9 m/s kPa observed XA/PES effect pH on HA neat membranes. rejection performance were compared with commercial available
