Study Of Bi-Functionalized Laterite Soil In Treating Dye Wastewater Through Coagulation-Flocculation And Degradation
Raw laterite soil collected from bukit merah, perlis, malaysia went through decolorization pre-treatment before being used as coagulant-flocculant. This key material is dominated by silica component (36.30 %), followed by aluminum (27.10 %) and ferric (26.86 %). Silica was activated at the acidic...

| description | Raw laterite soil collected from bukit merah, perlis, malaysia went through
decolorization pre-treatment before being used as coagulant-flocculant. This key
material is dominated by silica component (36.30 %), followed by aluminum (27.10 %)
and ferric (26.86 %). Silica was activated at the acidic region (ph 2) which allowed
the silica to cleave the dye molecular structure through substitution, electrical double
layer compression and charge neutralization. Meanwhile, aluminium and ferric act as
nauxiliary agents in the coagulation-flocculation process. Laterite soil was able to
remove: acid orange 7 with 99.50 % at dosage of 14000 mg/l; methylene blue with
99.61 % at dosage of2500 mg/l; methyl orange with 99.11 % at dosage of9000 mg/l,
cibacron brilliant yellow 3g-p with 99.46 % at dosage of 8000 mg/l and reactive red
120 with 99.53 % at dosage of 6000 mg/l. This project has provided a new insight
into an effective dye degradation using a new class of natural coagulant-flocculantnalural
resources. |
