Abstract Environmental pollution due to development in modern industrial practice is one of the most significant problems of this century. Heavy metals are major toxic pollutants with serve health effect on human. The study of removal of heavy metals Pb (II), Zn (II) and Cd (II) from stimulated waste water by batch adsorption experiments with natural adsorbent for effective removal of Pb (II), Zn (II) and Cd (II) ions. The main parameters influenced the Pb (II), Zn (II) and Cd (II) adsorption process such as percentage recovery, initial metal concentration, effect of adsorbent dosage, metal ion concentration, effect of contact time and effect of pH was studied in batch experiments. The experimental results were analyzed by using Langmuir adsorption isothermal and Freundlich adsorption isothermal model. The kinetic data well described by the pseudo first order kinetic model. The thermodynamic parameters such as ΔH, ΔG and ΔS also determined. Annona muricata (soursop) fruit husk (AMFH) powder was successfully employed for removal of Pb (II), Zn (II) and Cd (II) ions from waste water and the techniques will be appears industrially applicable and feasible

Key words ; Adsorption, Annona muricata fruit husk powder, Pb (II), Zn (II) and Cd (II), Kinetics, Thermodynamics, Adsorption isotherms.
