Abstract

Sodium oxalate crystals grown in aqueous sodium hydroxide solutions with different concentrations were characterized by optical and atomic force microscopy to examine their morphologies. Experimental results indicated that a high concentration of sodium hydroxide had a dramatic effect on reducing the size of sodium oxalate crystals. A nitrogen gas adsorption technique was employed to quantify the change of specific surface area of sodium oxalate. A two dimensional image analysis technique was also employed to estimate surface area and the crystal size distribution of sodium oxalate.
