Abstract
A rapid analytical procedure of limestone has been investigated. In this method, calcium carbonate and magnesium carbonate are determined by disodium ethylenediaminetetraacetic acid titration ; and ferric oxide, aluminum oxide and silicic anhydride are determined by photometry. The precision and accuracy in this method are in good agreement with the A. S. T. M. value. Ten samples can be determined by one worker in one day. The time to analyse is one-forth and expense is one-half as compared with the former method. It can be applied to analyse similar materials, such as cement and dolomite.
