| Abstract: | In this study, removal of chromium (VI) from aqueous solution using Tamarindous indicia seeds has been investigated. The effects of pH, contact time, exchanger dose, have been studied at ambient temperature (25°C ± 2°C). The equilibrium process has been described by the Langmuir isotherm model with adsorption capacity for chromium (VI). The Tamarindous indica seeds are subjected to different modification methods (pulverization, formaldehyde and sulphuric acid treatment) and adsorption capacity of modified Tamarindous indica seeds for metal ion is obtained. The maximum exchange level have been attained 99% at pH 6.5 with exchanger dose 3.5 g and contact time 30 min. Method is applied for removal of chromium from industrial effluents. |
