3 Method summary

After the sample is dissolved in a nitric acid-sulfuric acid mixed solution and diluted to a certain volume, the sample solution is introduced into a plasma flame, and the test is to be tested. The intensity of the emission spectrum of the element is determined from the calibration curve.

4 reagents

4.1 Unless otherwise specified, the reagents used in this method are of analytical grade, and the test water is deionized water. 4.2 Nitric acid-sulfuric acid mixed solution. Measure 8 mL of nitric acid (ρ1.42g/mL) and 40mL of sulfuric acid (ρ1.84g/mL), dilute with water until 1L. 4.3 Pure manganese. the benchmark, the mass fraction is greater than 99.90%. 4.4 standard solution 4.4.1 Iron standard solution. 1 mg/mL. 4.4.2 Silicon standard solution. 0.5mg/mL. 4.4.3 Phosphorus standard solution. 0.05mg/mL. Accurately transfer 5.00mL of phosphorus standard stock solution (1mg/mL) into a 100mL volumetric flask, dilute to the mark with water, and mix. 4.4.4 Manganese standard solution. 50mg/mL. Accurately weigh 5.0000g of pure manganese (4.3) in a 250mL beaker, add the nitric acid-sulfuric acid mixed solution (4.2), and heat until dissolved. The solution was completely cooled, transferred to a 100 mL volumetric flask, and brought to volume. 4.4.5 Standard series solution. Divide 4.00 mL of manganese standard solution (4.4.4) into 7 50 mL volumetric flasks, and add iron standard solution (4.4.1) according to Table 1, respectively. Silicon standard solution (4.4.2), phosphorus standard solution (4.4.3). Dilute to the mark with water. ......
