Abstract
Polypyrrole nitrogen porous carbon composite (PP/N-PCC) was prepared from molasses of the sugarcane industry. PP/N-PCC was characterized and used in the cadmium removal from the aqueous feed in a column system. The inlet metal concentration, flow rate, bed depth and pH were studied. Removal percent was reached 71.45% with a sorption capacity of 233.54 mg/g at pH5, 10 ml/min, and 7.5 bed depths. The column system was modelled using Thomas, Adams-Bohart and Yoon-Nelson kinetic models. The higher R

> 0.98 indicates that the Thomas model appeared to a well-fitting with the experimental outcomes. PP/N-PCC adsorbent appeared well recycled up to 8 cycles indicating the economic feasibility of PP/N-PCC in the separation of Cd (II) ions from liquid wastes.
