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 ...
