| titleOfInvention | Method of determining calcium chloride in air |
| abstract | The invention relates to methods for determining calcium chloride in the air and involves passing an air sample through a filter, extracting from the filter, introducing into the solution obtained chemical reagents - thiodiphenylamine and copper sulfate, which are injected to a concentration of 0.0035-0.014 and 0.006-0.008%, respectively, boiling for 30–40 min and subsequent photometry in an alcohol – acetic acid medium. The sensitivity of the determination of 2 µg of calcium chloride in the sample, the accuracy of 10-12%. 2 tab. |
