This study focused on using native locust beans (Parkia biglobosa ) hulls as an adsorbent of chromium ion from its aqueous solution by batch mode process, Atomic absorption spectrophotometer(AAS) was used in determining the metals concentration. Four factors affecting heavy metals sorption; pH,sorbent dosage, initial concentration and contact time were studied at 30±2°c. Optimum chromium ions extirpation was attained at pH 6 and 91.94% of chromium (VI) ions were removed in the first 60mins. Equilibrium sorption isotherms were evaluated, Freundlich model and Langmuir model results proved favourable sorption with the correlation coefficient (R2)of 0.9784and 0.9492 respectively,but former isotherm equation better-definedadsorption process as compared to latter isothermequation. Lagergren pseudo-first-order and Ho pseudo-second-order kinetic models were employed, but chromium (VI) ions adsorption was better explained by Ho pseudo-second-order model
