Catalytic thermolysis in treating Cibacron Blue in aqueous solution: Kinetics and degradation pathway
Claire Xin Hui, Su; Teng, Tjoon Tow; Wong, Yee Shian; Norhashimah, Morad; Mohd Rafatullah (Elsevier Ltd., 2016-03-01)A thermal degradation pathway of the decolourisation of Reactive Cibacron Blue F3GA (RCB) in aqueous solution through catalytic thermolysis is established. Catalytic thermolysis is suitable for the removal of dyes from ... -
Coagulation-flocculation of azo dye acid orange 7 with green refined laterite soil
Lau, Yen Yie; Wong, Yee Shian; Teng, Tjoon Tow; Norhashimah, Morad; Mohd Rafatullah; Ong, Soon-An (Elsevier B.V., 2014-06-15)A novel degradation pathway of Acid Orange 7 (AO 7) by laterite soil in coagulation process is suggested. AO 7 has a strong azo bond links with benzene and naphthalene rings. The rings in AO 7 can be cleaved during coagulation ... -
Degradation of cationic and anionic dyes in coagulation-flocculation process using bi-functionalized silica hybrid with aluminum-ferric as auxiliary agent
Lau, Yen Yie; Wong, Yee Shian; Teng, Tjoon Tow; Norhashimah, Morad; Mohd Rafatullah; Ong, Soon-An (Royal Society of Chemistry, 2015)Cationic dye (methylene blue) and anionic dye (methyl orange) degradation in the coagulation process was demonstrated. The key material was a natural coagulant-laterite soil dominated by a silica component, while aluminum-ferric ... -
A novel pretreatment method of lignocellulosic material as adsorbent and kinetic study of dye waste adsorption
Ling, Wei Low; Tjoon, Tow Teng; Anees, Ahmad; Norhashimah, Morad; Yee, Shian Wong (Springer Science+Business Media B.V., 2010)Sulphuric acid-modified bagasse has been used as low-cost adsorbent for the removal of methylene blue (MB) dye from aqueous solution. In order to remove organic compounds that contribute to chemical oxygen demand (COD), ... -
Suspended growth kinetic analysis on biogas generation from newly isolated anaerobic bacterial communities for palm oil mill effluent at mesophilic temperature
Wong, Yee Shian; Teng, Tjoon Tow; Ong, Soon-An; Norhashimah, Morad; Mohd Rafatullah (Royal Society of Chemistry, 2014)The anaerobic degradation of palm oil mill effluent (POME) was carried out under mesophilic temperature in an anaerobic suspended growth closed bioreactor (ASGCB). Monod model was applied to describe the kinetic analysis ...
