In the sugar industry analytical practice it is necessary to remove nonsucrose compounds from samples in order to determine sucrose content by polarimetric procedure. These mentioned compounds are removed by sedimentation after adding lead salts. Lead is considered as one of outstandingly strong pollutant of human environment and the living world as a whole. Ways of its environment presence are various. Some industrial branches are very close to this top including on this level even the sugar factories. Toxic effects of lead salts and the intensified concern for protecting the environment imposed the need for finding new sedimentation agents. In this work the influence of molasses quality on nonsucrose compounds sedimentation by aluminium-sulphate was examined. Optimum values of the parameters influencing the sedimentation process were determined. Best results were obtained with aluminium-sulphate at concentration of 0.1227 mol Al/dm3 and pH 6.0
