| Summary: | The implementation of the pore-forming agent in the polymeric membrane has been applied for ages in
enhancing the characteristics and performance of mixed matrix membrane. In this work, chlorophyll
extracted from spinach has been used as an additional pore-forming agent alongside polyethylene glycol
(PEG) to improve the polysulfone’s pore structure (PSf) mixed matrix membrane. The effect of chlorophyll
was investigated in terms of characteristics and performance of the mixed matrix membrane. As a result,
the cross-section morphologies show that the pore structure was enhanced significantly inside the mem�brane structure for 0.25 wt% chlorophyll concentration, thus resulted in better hydrophilicity, surface
roughness, and membrane porosity value. Plus, the permeation and rejection performance was increased
drastically due to the pore formation inside the mixed matrix membrane structure. These results prove
that the addition of chlorophyll with low concentration managed to improve the characteristics and per�formance of the fabricated mixed matrix membrane. |
