Abstract : The effect of low-molecular-weight organic acids (LMWOA) on desorption of chromium in soil contaminated with leather tanning industry waste water has been conducted. The aims of this research are to analyze the soil contamination around industry area, to study the physicochemical soil properties, and to investigate the effect of low molecular weight organic acids (citric acid, tartaric acid, and oxalic acid) on chromium desorption from the soil. The soil samples used in this study were collected from two different distances from the waste water sources. These soil samples were analyzed by X-ray diffraction spectroscopy (XRD) and Fourier-transform infrared spectroscopy (FTIR), and then determine their total organic compound, the content of chromium and cation exchange capacity (CEC). In the desorption part, the effect of LMWOA concentration, pH level and time variation were investigated and measured using atomic adsorption spectrophotometry (AAS) method. The results showed that the soil samples 1 and 2 had the chromium content at 1,402 mg kg-1 and 1,071 mg kg-1, respectively. Soil sample 1 had a higher value of CEC and total organic carbon than soil sample 2. In the chromium desorption process, there is a tendency of higher concentration of LMWOA desorbed the higher amount of chromium metal. The effective desorption occurred at the acid condition. For the kinetics study of metal desorption from soil samples in the presence of LMWOA, citric acid produced higher desorption rate constant (high k-value) than oxalic and tartaric acids. © RAS?YAN.
