Abstract

This research aims to study the initial study in using ZA industrial solid wastes, as raw material for the manufacture of calcium carbonate (CaCO3) with the addition of carbon dioxide gas (CO2). Materials - The materials used include: Solid Waste, Gas, Carbon dioxide (CO2), HCl, sakarosa PP Indicator (Phenol Phtalein) The instrument used is a CO2 gas cylinders, safety tubes, three-neck flask as a batch reactor, mixer, electric mixer motor, stative + holder, thermometer, regulator, electric heaters, Orifice meter, electric ovens, Furnace, Glass Beaker, Measuring cup, Balance Sheet analytic. The process of research to produce CaCO3 with raw materials ZA industrial solid waste through 3-stage process, namely process kaisinasi, hidratasi process and the process of carbonation. The results can be concluded that the products produced by the process of CaCO3 kaisinasi, hidratasi and carbonation, the optimum conditions of high, namely 94.1%. The increasing concentration of Ca(OH)2 then the conversion will tend to rise. But the concentration of Ca(OH)2 that the conversions generated are too thick will tend to fall. The longer the reaction time the higher the conversion. But at a certain reaction time the conversion will continue with increasing time (constant). Carbonation process shows the best conditions on concentration of Ca (OH) 2 35 gram/500 ml. 120 minutes reaction time and reaction temperature 30oC so that the conversion obtained at 96.44438%
