Abstract

The invention provides a method for detecting iron content in calcite and dolomite, and relates to the field of detection of iron content in calcite and dolomite, wherein the raw materials comprise hydrochloric acid, hydrofluoric acid, anhydrous sodium carbonate and boric acid, and the method comprises the following steps: (1) instrument preparation, (2) reagent preparation, (3) sample selection,(4) reagent grinding and dissolving, and (5) colorimetry. The invention designs a method for detecting the content of iron in calcite and dolomite. A superior pure reagent is adopted to replace an analytically pure reagent, so that in the sample treatment process, interference of trace iron elements brought by the analytically pure reagent on a monitoring result is reduced, and thereby the data accuracy is improved, the detection result is stable, detection data can be reported in time, and the detection result is scientific and accurate.

Description

technical field [0001] The invention relates to the field of iron content detection in calcite and dolomite, in particular to a method for detecting iron content in calcite and dolomite. Background technique [0002] At present, the incoming raw materials are calcite and dolomite, and the iron content detection structure fluctuates at different times. The detection results cannot be confirmed in time and the supplier has doubts about the monitoring results. A second review is required, which affects the speed of the detection report. Therefore, the work Personnel improve the inspection method to solve the above problems. [0003] The newly researched detection method utilizes the increased sampling base, the sampling standard of the quadratic quartering method, and at the same time, the purity of the pharmaceutical reagents is changed to improve the stability and accuracy of the detection results. Contents of the invention [0004] The purpose of the present invention is ...
