Abstract
Waste generated from ZA fertilizer in the form of calcite crystal flour contains a lot of CaO so that it can be used as raw material for the manufacture of Precipitated Calcium Carbonate (PCC), which is currently being developed as an advanced material measuring less than 100nm, namely nano-PCC. The formation of PCC used bottom-up coprecipitation method through chemical synthesis by mixing CaCl2 filtrate solution and ethylene glycol polymer solution. This research was conducted to determine the effect of the ratio of moles of CaCl2 and ethylene glycol with temperature variables to the particle size of CaCO3. PCC synthesis was carried out in several stages, namely material preparation, mixing, pH adjustment, precipitation, and drying. The variables used were the ratio of moles of CaCl2: ethylene glycol (1:8); (1:9); (1:10); (1:11); (1:12) and temperature variables (30oC; 40oC; 50oC; 60oC; 70oC). The results showed that the ratio of moles of CaCl2: ethylene glycol and temperature greatly affected the results of CaCO3 particle size, where the smaller the ratio of moles of CaCl2: ethylene glycol and the higher the temperature, the size of the PCC particles formed was more nano. The best results were obtained at the mole ratio of CaCl2: Ethylene Glycol (1:8) at a temperature of 70ºC with a nano-PCC particle size of 5.044 nm and a yield of 75.9%, and obtained aragonite-calcite crystals with rod and prismatic shapes and a CaCO3 content of 81.69%
