Abstract

• Asbestos Containing Material (ACM) has long been recognized as hazardous waste due to the presence of chrysotile. Chrysotile ((Mg, Fe)3Si2O5(OH)4)), a natural phyllosilicate that belongs to the serpentine group has a fibrous crystal structure that provides ACM mechanical strength and heat resistance but causes fatal lung diseases. Therefore, it is very important to ensure safe removal and disposal of ACM. The physical and chemical structure of chrysotile can be altered by reacting it with CO2 to form MgCO3. This serves the dual purpose of reducing the atmospheric CO2concentration and alters the fibrous structure of ACM to render it harmless. To determine structural and chemical changes of ACM, single step carbonation experiments where performed where reaction fluid (DI Water, 0.1M Na-oxalate, 0.1M Na-acetate or 1.0M Na-acetate) and ACM or pure serpentine are reacted in the presence of 150 atm of CO2 at high temperatures (Tmax = 185°C) for 3 hours in a high temperature, high pressure batch reactor. Xray Fluorescence in conjunction with Electron MicroProbe Analysis, Thermogravimetric Analysis and Total Inorganic Carbon Analysis revealed changes in the chemical composition of ACM. Changes in particle diameter, pore volume and morphological features were determined using Particle Size Analyzer, BET and SEM respectively. (literal)
