The present investigation attempted to analyze the biosorption behavior of novel biosorbent, Amphiroa flagillisma brown algae powder, for the removal of Cr+3 from solution against the function of initial metal ion concentration, pH, temperature, sorbent dosage and biomass particle size. The maximum biosorption was found to be 98.51% at pH 4.7 and biosorption capacity (qe) of Cr+3 is 11.04 mg/g. The Langmuir, Tempkin and Freundlich equilibrium adsorption isotherms were studied and observed that Langmuir model is best fitted than the other model with correlation co-efficient of 1.0. Kinetic studies indicated that the biosorption process of Cr+3 well followed the pseudo second order model with R2=1.0. The process is exothermic and, spontaneous nature of the process. The chemical functional groups ��?OH, CH2 stretching vibrations, C=O of alcohol, C=O of amide, P=O stretching vibrations, -CH, were involved in the process. The XRD pattern of Amphiroa flagillisma brown algae powder was found to be mostly amorphous in nature. The SEM studies showed Cr+3 biosorption on selective grains of the biosorbent. It was concluded that Amphiroa flagillisma brown algae powder can be used as an effective, low cost, and environmentally friendly biosorbent for the removal of Cr+3 from aqueous solution.
