Burmese Grape Leaf Extract (BGLE), a low cost adsorbent was studied for cadmium (Cd(II)) removal from metal solutions and natural water samples. Batch adsorption studies were carried out to examine the influence of contact time and initial metal concentration after characterization under scanning electron microscopy (SEM). Cd(II) adsorption on to BGLE was best explained by pseudo-second order kinetics (R2 = 0.99) and best fitted with Langmuir isotherm model (R2 = 0.76). Beside the selective adsorption activity of BGLE towards Cd(II), only 0.1 g of BGLE have shown effective adsorption of these ions with a maximum adsorption capacity (qm) of 44.72 mg g−1. This study was a unique combination of laboratory experiments and field implication.
