ABSTRACT:
The adsorption
of fast yellow dye onto dried biomass Padina pavonica was studied in
batch experiments. The amount of dye adsorbed (mg/g) was increased with the
increase in initial dye concentration. An equilibrium time of about 90 min was
achieved for dye concentrations ranging from 5 to 160 mg/L with maximum removal
percentage of 73.2%. Pseudo-first and second order kinetic models have been
used to analyze the adsorption data. The pseudo second-order kinetic model
adequately described the adsorption data with correlation coefficient between
0.96 and 1.084. Fourier transform infra-red analysis demonstrated the chelating
character of the dye molecule to different functionalities groups of the alga. Stirring
speed higher than 50 rpm revealed no significant changes in dye adsorption.
Temperature ranging from 15℃ to 65℃ showed stability followed by a decrease in
adsorption. Scanning electron microscopy of adsorbent particles showed a high
surface porosity allowing the free passage of dye molecules.
