The use of fine beach sand to remove hazardous Chromium [VI] ions from aqueous solutions was investigated. Removal of chromium ions from stock solution of known concentration of Potassium dichromate was carried out by two sand samples, one pretreated with 70% nitric acid and one washed with distilled water. The experiment was carried out as a function of pH, where the nitric acid pretreated sand had a pH=1, and the water-pretreated sand had a pH=7. The experiment was carried out at room temperature (31°C). The adsorption time for both the solutions was 180 minutes. The main principle of this experiment was the adsorption of chromium [VI] ions to the sand particles. The rate of removal of chromium [VI] ions was observed both qualitatively as well as quantitatively. Higher removal of chromium ions was obtained at pH=1 compared to pH=7 sand samples. For Cr [VI], the Langmuir isotherm gave the best fit for adsorption. The results are discussed in terms of the chromium species present in the solution and the effect of contact time and pH on the rate of adsorption and removal efficiency has been studied.
