Abstract

In this study, a template synthesis was employed for preparing calcium hydroxide from industrial eggshell waste. Both effect of template chemicals e.g. ethanol, isopropanol, butanol and pentanol, and synthesis temperatures on properties of calcium hydroxide were systematically investigated. The results from N2 adsorption onto synthesized calcium hydroxide at -195 °C indicated that kinematic diameter of template alcohols played an important roles on specific surface area of synthesized calcium hydroxide. Synthesis of calcium hydroxide at room temperature using isopropanol as template exhibited high specific surface area of 47.96 m2/g, which was higher than conventional synthesized calcium hydroxide. In addition, synthesizing of calcium hydroxide and further activation at high temperature led to decrease of specific surface area of calcium hydroxide.
