Synthesis and Modification of Nano-Precipitated Calcium Carbonate (PCC) with Addition of Ethylene Glycol

ZA fertilizer waste (Ammonium sulfate) is generated from the industrial process of producing fertilizer. The contains very high calcium and has potential to be used as a raw material in manufacture Precipitated Calcium Carbonate (PCC). PCC with certain qualities can developed field advanced materials, size modification into nanoparticles. One method produce nanoparticles using coprecipitation method, help polymer solution. This study aims Nano-PCC by finding best conditions CaCl2: Ethylene Glycol mole ratio stirring speed. synthesized reacting HCl form CaCl2 Then, solution mixed ethylene glycol prevent particle agglomeration so that obtained will smaller. mixture then reacted Na2CO3 precipitated carbonate In this study, variables were (1:12, 1:14, 1:18, 1:20) speed (350, 500, 650, 800, 950 rpm). Based on PSA analysis, at smallest 1:12, rpm was 51.83 nm. Scherrer’s calculations XRD, 48.25 SEM analysis showed crystals formed dominated vaterite crystals, range 55.71-607.79
