Abstract

ABSTRACT Adsorptif stripping voltammetry (AdSV) has been proved to be a simple and effective method for determination of heavy metal ionsusing 0,6 mM calcon as ligand on pH 6 and developed a lot of attention right now is take advantage of the ability to accumulate heavy metals by biomaterials that are relatively economical and easy to obtain. Nypa fruticans Merr shell, Arenga pinnata Merr shell and Phaseolus lunatus shell was used for removal Cd(II) and Zn(II) ions from aqueous solutiuon. The optimum condition was achieved for Cd(II) and Zn(II) on pH 6, Determination of the optimum conditions measurements of Cd(II) and Zn(II) simultaneously with adsorptive stripping voltammetry is pH 6, contact time 60s, concentration 50 mg/L. accumulation potential of -1.2V, and time accumulated 90s. The concentration of the metal content of Cd(II), and Zn(II) are 0.502mg/L. and 0.602mg/L for Nypa fruticans Merr shell and 1.026mg/L. 1.398mg/L for Arenga pinnata Merr shell and 2.098mg/L, 3.675mg/L for Phaseolus lunatus shell. Keywords: Adsorptif stripping voltammetry, Biosorption, heavy metal, Nypa fruticans Merr shell, Arenga pinnata Merr shell, Phaseolus lunatus shell.
