Degradation of synthetic dye wastewater by using combined anaerobic-aerobic and aerobic sequencing batch reactors
Murali, V.; Ong, Soon-An; Nasrul, Hamidin, Dr.; Wong, Yee Shian; Ho, Li Ngee; Khairul Anuar, Pakri (Universiti Malaysia Perlis (UniMAP), 2012-06-18)Azo dyes are the dye used by the majority of the textile industries. The treatment options for this azo dye are physical, chemical and biological methods. The aim of this study was to assess the performance of dye ... -
Enhanced photocatalytic activity of fish scale loaded TiO 2 composites under solar light irradiation
Ho, Li Ngee; Ong, Soon-An; Hakimah, Osman; Chong, Fong-Mun (Elsevier B.V., 2012-06)Fish scale (FS) loaded TiO2 composites were investigated as photocatalysts in degradation of Methyl Orange under solar light irradiation. Composites were prepared through sol-gel method by varying mass ratio of TiO2/FS at ... -
Photocatalytic degradation of reactive black 5 by fish scale-loaded TiO 2 composites
Ho, Li Ngee; Ong, Soon-An; Yee, Lin See (Springer Science+Business Media B.V., 2012-09)Titania and TiO 2/fish scale composites at different mass ratios (90:10, 70:30, and 50:50) were prepared by sol-gel method for application as photocatalysts in this study. Fish scale, synthesized TiO 2, and TiO 2/fish scale ... -
A simple one-step anodising method for the synthesis of ordered porous anodic alumina
Voon, Chun Hong; Mohd Nazree, Derman, Dr.; Uda, Hashim, Prof. Dr.; Khairel Rafezi Ahmad, Dr.; Ho, Li Ngee (Taylor & Francis, 2014)Porous anodic alumina (PAA) has been produced on aluminium substrate by single-step anodising at 50 V in 0.3 M oxalic acid at 15°C for 60 min. The highly ordered pore and cell structure was achieved by subjecting the PAA ... -
Surfactant-free synthesis of copper particles for electrically conductive adhesive applications
Ho, Li Ngee; Nishikawa, Hiroshi (TMS, 2012-09)In this study, a simple one-step microwave-assisted method was developed to synthesize Cu and Cu-Ag particles for application in electrically conductive adhesive (ECA). The particle size of the obtained Cu particles was ...
