Abstract: Here, the potentiality of low cost, environment friendly and abundantly available bio-adsorbents prepared from rice husk (RHA) and saw dust (SDA) are reported for the removal of toxic anionic dye, Amaranth dye (AMD) from the artificial wastewater. The influence of the parameters that may affect the removal process including contact time, pH, adsorbent dosage and initial dye concentration was investigated in order to properly select the removal process optimization parameters. The adsorption kinetic and isotherm of removal of AMD was also carried out. Kinetic studies have shown that the absorption process can be explained smoothly by the pseudo-second sequence, where the absorption of AMD strongly follows Langmuir's isothermal models. The adsorption isotherm indicates the maximum adsorption capacities of AMD on RHA and SDA are 74.07 and 78.13 mg g-1, respectively.
