The ability of Muntingia calabura L. and Andrographis paniculata leavesto remove Zn(II) ions in wastewater on some parameter test such aseffect of pH solution, initial metal concentration, contact time and biosorbent mass were studied. The optimum conditions forMuntingia Calabura L leaveswere obtained at pH 4, initial concentration of Zn(II) Ion is 750 mg/L for 30 minand 0.1 g of biosorbent mass, while Andrographis paniculata leavesobtained at pH 6, initial concentration of Zn(II) Ion is2400 mg/L for 15 min and 0.1 g of biosorbent mass. Isoterm adsorpstion found for Muntingia calabura L. and Andrographis paniculata leaves were Freundlich and Langmuir respectively. Based on this research, the ability ofAndrographis paniculata is better than Muntingia calabura L. leaves on removing Zn(II) ions. Metal ion concentrations were measured by using Atomic Absorption Spectroscopy (AAS). Maximum adsorption capacity of Zn(II) by using Andrographis paniculata and Muntingia calabura Lleaves were 71.66 mg/L and 27.6350 respectivelywhile the morfology surface of biomaterialwere performed using Scanning Electron Micrograph (SEM) and Fourier Transform Infra Red pectroscopy (FT-IR) were used to describe theinteraction of Zn(II) ions with the funtional groups of biosorbents to the formation of discrete aggregates on the biosorbents surface.
