More Information
Summary:The invention discloses a rapid system analysis for limestone and dolomite. The rapid system analysis comprises the following steps: putting a sample into a platinum crucible and firing at 1000 DEG C; determining the ignition loss; dissolving the sample with the determined ignition loss by use of hydrochloric acid and perchloric acid and evaporating until white smoke is generated; adding water to dilute and filtering; determining the content of silicon dioxide of a filtering cake by using a weight method; putting the filtering solution into a 250ml volumetric flask; enabling the volume to be constant by use of pure water and taking the liquid to respectively determine the contents of elements including CaO, MgO, FeO3, Al2O3, P2O5, K2O, Na2O and the like. The rapid system analysis for the limestone and the dolomite is rapid in determination speed and accurate in data and can be used for saving about one half of relative reagents.
