Chemical Analysis of Mixed Lead - Zinc Concentrate Part 12. determination of thallium content Inductively coupled plasma mass spectrometry And inductively coupled plasma atomic emission spectrometry1 ScopeThis part of YS/T 461 specifies the method for the determination of thallium in mixed lead-zinc concentrates. This part is applicable to the determination of thallium in mixed lead and zinc concentrates. Method 1 has a measurement range of 0.000050% to 0.010%; Method 2 is measured The range is 0.0050% ~ 0.10%. Section 1 Scope Cross Section Method 1 is an arbitration method. 2 Method 1 Inductively Coupled Plasma Mass Spectrometry 2.1 Method Summary The samples were decomposed by hydrochloric acid, nitric acid and sulfuric acid. The samples were measured on an inductively coupled plasma mass spectrometer with 193Ir as internal standard. Calculate the amount of thallium in the sample. 2.2 Reagents In the analysis only use identified as excellent grade pure reagent, the water used as a water. 2.2.1 Hydrochloric acid (ρ1.19g/mL). 2.2.2 nitric acid (ρ1.42g/mL). 2.2.3 sulfuric acid (ρ1.84g/mL). 2.2.4 nitric acid (1 1). 2.2.5 nitric acid sulfuric acid mixed acid (1 1). 500mL nitric acid (2.2.2) while stirring 500mL sulfuric acid (2.2.3), after cooling use. 2.2.6 Thallium standard storage solution. Weigh 0.2795g thallium oxide (wTl2O3 > 99.99%) placed in.200mL beaker, cover dish, Slowly add 25mL nitric acid (2.2.4) dissolved at low temperature, drive out the nitrogen oxide, remove and cool to room temperature, wash the dish and cup wall with water, 250mL volumetric flask, diluted with water to the mark, mix. This solution 1mL containing 1mg thallium. 2.2.6.1 Thallium standard solution A. Thallium standard storage solution (2.2.6) diluted to thallium concentration of 100ng/mL, 2% nitric acid as the medium. 2.2.6.2 thallium standard solution B. thallium standard solution A diluted to thallium concentration of 10ng/mL, 2% nitric acid as the medium. 2.2.7 internal standard solution. 10μg/L193Ir solution, with 2% nitric acid as the medium. 2.2.8 argon. wAr ≥ 99.996%. 2.3 Instruments Inductively coupled plasma mass spectrometer. resolution 0.1amu ~ 1amu; 205Tl isotope response value > 105. 2.4 Sample 2.4.1 Specimens shall pass through 0.074mm sieve. ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of YS/T 461.12-2016_English be delivered?Answer: Upon your order, we will start to translate YS/T 461.12-2016_English as soon as possible, and keep you informed of the progress.
