Chitosan beads have been used as an adsorbent calcium metal ion from wastewater by using adsorption process. The effect of contact time and concentration initial of calcium metal ion were investigated. The experiment data were analysis with kinetic and isotherm adsorption. The results showed that the adsorption of calcium metal ion is followed kinetic model of first order sorption reaching equilibrium and Langmuir isotherm model. The Adsorption capacity of calcium ion on chitosan nanobeads was 90,23. 10-4 mol/g and on chitosan flake was 10,15. 10-4 mol/g. © 2010 RJPBCS.
