Foreword

YS/T 738 "filler aluminum hydroxide analysis method" is divided into four parts. --- Part 1. Determination of pH; --- Part 2. Determination of soluble alkali content; --- Part 3. Determination of sulfide content; --- Part 4. Determination of viscosity. This is Part 3. This section drafted in accordance with GB/T 1.1-2009 given rules. The non-ferrous metal part by the National Standardization Technical Committee (SAC/TC243) centralized. This part of the Aluminum Corporation of China Shandong Branch, China Nonferrous Metals Industry Institute of Standards Metrology and Quality is responsible for drafting. This section drafted by the Aluminum Corporation of China Shandong Branch. The main drafters of this section. Tian Rui, Xu good text, Chen Hongyun. Analysis of aluminum hydroxide filler Part 3. Determination of sulfide content

1 Scope

YS/T in this part 738 specifies the method for determination of aluminum hydroxide filler in sulfide. This section applies to the filler with aluminum hydroxide - Determination of sulfide. Measuring range. sulfide ≤5μg/mL.

2 Method summary

The sample is decomposed acid, hydrogen sulfide gas evolution and the role of lead acetate paper sealed, lead sulfide stain, spot color with its depth, determination Sulfide content. The main reaction. S2- 2H = H2S ↑ H2S Pb2 = PbS ↓ 2H.

3 reagents Instrument

3.1 Hsu carbonate measuring device. 3.2 hydrochloride (11). 3.3 lead acetate solution 100g/L. 3.4 sodium sulfide (Na2S · 9H2O). 3.5 sodium hydroxide. 3.6 pairs of hydroquinone. Sulfide 3.7 Standard solution. 0.749 dissolving sodium sulfide (3.4) in deionized water, was added 10g sodium hydroxide (3.5) of benzene and 0.5g After the diol (3.6), to be completely dissolved in deionized water to 1000mL volumetric flask, shake spare. This solution 1mL quite 0.1mg sulfur. Of this solution 5.00mL, in 500mL volumetric flask to the mark with deionized water will shake up. This solution 1mL considerable sulfur 1μg. 3.8 Preparation of lead acetate test paper. the rapid quantitative filter paper cut φ22mm round, soaked in lead acetate solution (3.3) in, 15min after taking Out. In the absence of sulfides in the air to dry, store in a brown bottle aside. 3.9 Preparation of standard stain. Take 1μg/mL standard solution of sulfur (3.7) 1.00mL, 2.00mL, 3.00mL, 4.00mL, 5.00mL order placed Hsu carbonate measuring device (3.1), the measuring device installed at the top with a lead acetate paper (3.8) sealing well. From the drop Hydraulic bucket mouth were slowly added hydrochloric acid (3.2) 20mL, fighting and blocking solution with hydrochloric acid (3.2) 10mL, close the piston. Plus on a hot plate at a low temperature Heat boil 1min, cooling, remove the paper and set aside. The strip corresponds sulfide 1μg/mL, 2μg/mL, 3μg/mL, 4μg/mL, 5μg/mL.

4 Sample

The sample was placed in a closed container, the capacity of the container to be almost full sample is appropriate.
