Dissolution kinetics of chemically pure quicklime in the presence of various anions

1 Introduction

Pure quicklime (CaO) is a white, solid material at room temperature, prepared by the thermal decomposition of limestone (CaCO3). Of the heavy industrial chemicals, lime is second only to sulphuric acid in the amount produced. It is commonly used as an industrial base and plays an important role in many practical applications such as flue gas desulphurization, potable water treatment, paper manufacturing, cement production and steel and ferro-alloy production processes, where it can be used as a flux to remove impurities in refining steel. Another well-known use is to improve the...
