Optimization of phenolic removal using oil palm empty fruit bunch (OPEFB) biosorbent
(Universiti Malaysia Perlis (UniMAP), 2013-06)
This study investigates the optimization of biosorption of phenolic compound using
treated OPEFB biosorbent. The surface of biosorbent was modified by physical or
chemical treatment. The biosorption capacity for ...
Extraction optimization of phenolic compond from Zingiber Aromaticum Rhizome using pressurized hot water extraction (PHWE)
(Universiti Malaysia Perlis (UniMAP), 2013-06)
Pressurized hot water extraction (PHWE) method was implemented in order to reduce
the usage of organic solvent in extracting phenolic compound from the rhizome of
Zingiber aromaticum. At first, the screening studies using ...
Preliminary study on the treated charcoal development from OPEFB for phenolic compound removal
(Universiti Malaysia Perlis (UniMAP), 2013-06)
Treated charcoals derived from oil palm empty fruit bunch (OPEFB) were
investigated to find the suitability of its application for removal of phenolic compound
in aqueous solution through adsorption process. For the ...
Development of Aqueous Two-Phase System (ATPS) to separate crude bioactive phenolics from phanerochaete chrysosporium biomass
(Universiti Malaysia Perlis (UniMAP), 2013-06)
Natural antioxidants demand has increased globally due to the advantages and effect in
various aspects, especially in pharmaceutical industry. Fungus Phanerochaete chrysosporium presents crude bioactive phenolics which ...
Total phenolic content and antiodant activity of G.obscurum
(Universiti Malaysia Perlis, 2011)
The natural value of the leaves of the Tebengau ‘Glochidion
obscurum’ was explored in this study. The leaf sample of these plant
species was collected at Pusat Agrotech Sungai Chucuh. Other than
