Adsorption of heavy metals by synthetic adsorbent will need higher cost compare to the other adsorbents. Thus, an alternative way of natural adsorbent is search by researcher to reduce wastewater management cost. Mango leaves recently has been investigated to remove heavy metal ions from aqueous solutions cause of its economic feasibility and availability in large quantity in Malaysia. The objective of this research is to investigate the potential of mango leaves as alternative adsorbent to adsorb Cd (II), Ag (II) and Fe (II) heavy metal ions from aqueous solution by find its kinetic and adsorption isotherm using batch techniques. The adsorbent and adsorbate prepared is used for testing the effect of removal of the ions by the variation parameters of solution pH (pH2, Ph4,pH6 pH8,pH10), contact time (40min,60min,80min,100min,120min), adsorbent dosage (0.1g,0.2g,0.3g,0.4g,0.5g) and initial concentration (20ppm,40ppm,60ppm,80ppm, 100ppm). The optimum ph=6, effective time and dosage of 120min and 0.3g is use through all parameters variation. All the experiments are using batch adsorption process and finalize by shake using rotary shaker and analyze using Atomic Absorption Spectroscopy (AAS). This adsorption case fit Langmuir isotherm with correlation coefficient of 0.997 for Mangifera indica leave and 0.999 for Mangifera odorata leave and satisfactory Pseudo-second order kinetic with correlation coefficient of 1 for all metal and adsorption constant range 0.0068 to 0.05486 g/mg.min for Mangifera indica leave and 0.0215 to 0.0418 g/mg.min for Mangifera odorata leave. Freundlich isotherm also fit well this adsorption case with the correlation coefficient of 0.997 for Mangifera indica leave and 0.999 for Mangifera odorata leave which is come after the Langmuir isotherm with the correlation coefficient of 0.998. This research approved that mango leaves can be used as an alternative adsorbent to reduce Cd (II), Ag (II) and Ag (II) ions from aqueous solution.
