Abstract:	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 °c. 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 entropby 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.
