The increase of industrial activities has intensified environment pollution .Today one of the most important subjects is water pollution with heavy metals such cadmium, lead, nickel and zinc which can be removed from water using different methods and sorbent .In this study sodium Alginate, which is extractedfrom brown algae, mixed with calcium chloride 0.5M containing Powder Activated Carbon (PAC) or Multi Wall Carbon Nanotube (MWCNTs) to build insoluble sphericalcalcium Alginate. The spherical adsorber with Activated Carbon or Multi Wall Carbon Nanotubewas used for separation of cadmium ions. The effect of pH shown that the best condition is in pH=6.
The kinetic of adsorption in different times were studied and registered. Next study was down for the maximum adsorption capacity of cadmium with spherical adsorber containing PAC and MWCNT. The results shown that the adsorption of PAC and MWCNT was 1.12 and 1.28 m mole/g respectively. The effect of amount of PAC and MWCNT were investigated. Atomic absorption spectrometer was used for determination of concentration of adsorbed of cadmium ions.
The results shown that the adsorption capacity of Cd(II) is higher in compare with reported data >pH
