Abstract

The Nypa fruticansMerr shell was used for removal of Cu (II), Pb(II), Cd(II) and Zn (II) ions from aqueous solution by batch adsorption method. Several variables such as effect of pH, contact time, concentration of toxic metal, stirring time and agitation speed on the absorption capacity of metals ion has been investigated. The optimum condition was achieved for Cu(II), Pb(II), Cd(II) and Zn(II) on pH 6, contact time 60s, concentration 50 mg/L. The Agitation speed of Cd(II), Cu(II), Pb(II) were 200 rpm and Zn(II) was 150 rpm.All metals ion concentration has been measured by using atomic absorption spectrometry. On te other hand functional groups present on the shell was measured using Fourier Transform Infra Red spectroscopy.
