This section applies to the determination of aluminum alloy with nickel content. Measuring range. 5.0% to 25.0%.2 Method summaryThe sample is dissolved with hydrochloric acid, sodium fluoride masking aluminum, iron and other interfering elements. In weak acid solution, an excess of EDTA accurate standard Solution of complex test solution nickel ions with xylenol orange as indicator, titrated with zinc standard solution remaining EDTA, determination of nickel content.3 ReagentsUnless otherwise indicated in the analysis using only the gifted class pure reagents and sub-boiling distilled water or potassium. 3.1 hydrochloride (11). Aqueous ammonia 3.2 (ρ = 0.90g/mL). 3.3 NaF saturated solution. Weigh 55g of sodium fluoride in the beaker, was added 1000mL of water, heated to boiling 30min, cooled, the upper layer solution It was transferred to a vial. 3.4 ammonium acetate solution (500g/L). 3.5 pairs nitrophenol solution (2g/L). XO 3.6 - solid sodium chloride indicator. xylenol orange Weigh 1g and 99g of sodium chloride in a glass mortar, mixed finely ground and stored at Reagent bottle. 3.7 zinc standard solution (0.025mol/L). Weigh 1.6348g zinc metal [w (Zn) ≥99.99%] in the beaker, add 30mL salt Acid (3.1), completely dissolved by heating, cooling, transferred to 1000mL volumetric flask, dilute with water to volume, and mix. 3.8 EDTA standard solution (0.025mol/L). 3.8.1 preparation. Weigh 9.3gEDTA beaker, 500mL of water was added and heated to dissolve completely cooled, filtered to 1000mL capacity Volumetric flask, dilute to the mark and mix. 3.8.2 Calibration. Pipette 20.00mL standard zinc solution (3.7) in 500mL conical flask, was added 10mL of hydrochloric acid (3.1), was added 50mL saturated sodium fluoride solution (3.3), 2 drops of p-nitro phenol solution (3.5), with ammonia (3.2) and to yellow, and then hydrochloric acid (3.1) adjusted 4 drops of colorless and excess, was added 5mL ammonium acetate solution (3.4), add a small amount of xylenol orange - solid sodium chloride indicator (3.6), with EDTA Standard solution (3.8.1) titration to the disappearance of the red solution was bright yellow as the end point. 3.8.3 Calculation. according to formula (1) calculate the concentration of EDTA standard solution. c = c1 · V1 (1) ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of YS/T 807.3-2012_English be delivered?Answer: Upon your order, we will start to translate YS/T 807.3-2012_English as soon as possible, and keep you informed of the progress.
