Masitah, H.; Nor Azzahra, S.
Adsorption of remazol brilliant pink (Red 3BS) dye from aqueous solution onto activated LLS
adsorbent was investigated in a batch study. Adsorption isotherm and kinetics study were
carried out by considering the effects of various parameter such as adsorbent dosage (0.2 g
- 2.0 g) initial concentration (25mg/L-125mg/L) and contact time (10 min - 180 min), also
effect of solution pH (2 - 12). Equilibrium data were fitted to Langmuir and Freundlich
isotherm models. The equilibrium data were best described by Langmuir isotherm with the
maximum adsorption capacity 2.945 mg/g. Furthermore, the kinetic model applied to
pseudo-second-order, which has the best fitted data. The result of this study showed the
potential of low cost of LLS agricultural waste material to adsorb the reactive dye pollutant
containing in wastewater system.

In this study, the adsorption of Reactive Orange 16 (R016) onto cross-linked chitosan/oil palm ash composite beads (CC/OPA) was studied in batch mode operation with respect to temperature and initial dye concentration. The adsorption of R016 onto cross-linked chitosan/oil palm ash composite beads increased with increasing temperature (30 - 50 °C) and initial dye concentration (50 - 500 mg/L). The Langmuir and Freundlich isotherms models were used to described the isotherm data; of which the Freundlich model described the isotherm data with high correlation coefficients. The monolayer coverage capacities of cross-linked chitosan/oil palm ash composite beads of R016 dye was obtained 303.1, 434.8 and 588.2 mg/g at temperature 30, 40 and 50°C, respectively. It was observed that the reactive orange 16 dye adsorption capacity of cross-linked chitosan/oil palm ash composite beads increased in the order 30 > 40 > 50°C. The pseudo-first-order and pseudo-second-order were applied to the experimental data and its was found that results of corelation coefficients, the adsortion kinetics obeys a pseudo-first-order.

Masitah, Hassan; Bassim, H. H.; Abdul Latif, A.
The effect of temperature on adsorption of reactive blue 19 (RB19) by cross-linked chitosan/oil palm ash composite beads was investigated. Temperature studied from range 30 to 50 0C. It was observed that the uptake of this dye increased with increasing in temperature. Results revealed that sorptions of reactive blue 19 (RB19) on cross-linked chitosan/oil palm ash composite beads was endotermic in nature. Thermodynamics parameters such as entrophy change, entalphy change and Gibb's free energy were found out to be 166.20 J/mol.K, 46.21 kJ/mol and -3.86 to - 7.15 kJ/mol, respectively.
