Arabic gum (AG) as an additive to the casting solutions of polysulfone (PS) was investigated in this work to increase the hydrophilicity of PS ultrafiltration membranes. Various AG loading (0.1-3.0 wt. percent) in PS/dimethylacetamide (DMAc) dope solutions were prepared to fabricate PS membranes using phase inversion technique. The hydrophilicity a...
