  7. Abstract:
  8. Cane sugar impurities cause reduse production sugar in cane sugar industry.These impurities include polysaccharide for example starch, dextran and inorganic ash constituent such as potassium, sodium calcium magnesium and silica .The amount of impurities in the cane sugar depend on many factors including variety , grooving conditions and regional climate. Removal of impurities from cane sugar juice by clarification is an essential part of process of raw sugar manufacture. This process is based on the addition of lime, phosphates and polyelectrolyte. In this study effect of the amount of lime, phosphates and poly electrolyte on removal of various impurities has been investigated.In addition Color is one of the important factors in determining the quality of sugar in cane sugar industries. In this study samples of activated carbon were successfully prepared by carbonization and activation of sugarcane bagasse, chemical activation was achieved by impregnating the prepared raw material with activating reagents (phosphoric acid. Characteristics of the activated carbons were determined using standard methods The PH, Moisture values for prepared carbons of bagasse were Lower, compared to CSX active carbons .but the Ash values for prepared carbons of bagasse were higher compared to CSX. Results are shown that ash value don’t effect on ash value in decolonization raw sugar liquor. Activated carbon’s ability to adsorb color from raw sugar was also investigated and compared to a commercial reference carbon. Results reveal that activated carbon produced from sugarcane bagasse has a significant potential in the sugar industry
