Foreword

YS/T 534-2007 "chemical analysis of aluminum hydroxide" is YS/T 534-2006 (formerly GB/T 6610-2003) amendments It is divided into five parts. --- Part 1. Determination of moisture content - Gravimetric method --- Part 2. loss on ignition - Gravimetric method --- Part 3. Determination of silica content molybdenum blue photometric --- Part 4. Determination of iron oxide content phenanthroline spectrophotometry Determination of sodium oxide content. Part 5 --- This is Part 1. The partial replacement of YS/T 534.1-2006 (formerly GB/T 6610.1-2003). This part is YS/T 534.1-2006 "Chemical analysis methods of aluminum hydroxide - Part 1. Determination of moisture weight method," the editor Finishing. The non-ferrous metal part by the National Standardization Technical Committee and centralized. This part of the Aluminum Corporation of China Zhengzhou Research Institute is responsible for drafting. This section drafted by the Aluminum Corporation of China Shandong Branch. The main drafters of this section. Chengya Juan, Zhang Wencheng. This part of the standard replaces the previous editions are. --- YS/T 534.1-2006 (formerly GB/T 6610.1-2003). Methods for chemical analysis of aluminum hydroxide Part 1. Determination of moisture content - Gravimetric method

1 Scope

This section provides the determination of aluminum hydroxide in water. This section applies to the determination of aluminum hydroxide in water. Measuring range. 1.00% to 20.00%.

2 principle of the method

Sample at 110 ℃ ± 5 ℃ drying 2h, to lose mass calculated moisture content.

3 Instrument

3.1 Analytical balance. accuracy 0.0001mg. 3.2 vacuum dryer. with the new desiccant activated alumina, the same vacuum dryer while cooling the appropriate number of weighing bottle. For example, the inner diameter 21cm vacuum dryer, while cooling the weighing bottle not more than six. 3.3 Oven. temperature can be controlled at 110 ℃ ± 5 ℃, can not be simultaneously dried in an oven other materials.

4 Sample

4.1 sample container should be filled with sealed, formerly known sample and mix well. 4.2 activated alumina activated. will be filled with activated alumina beaker was placed in an oven with a blower, drying at 300 ℃ ~ 350 ℃ 3h ~ 4h, removed, and immediately placed in a vacuum desiccator (3.2), cooled to room temperature before use. Activated activated alumina is generally used 6 times Determination of moisture. Step 5 Analysis 5.1 Sample Weigh 5.0g sample (4.1), accurate to 0.0001g. 5.2 Determination of the number of Independently measured twice and averaged. 5.3 Determination 5.3.1 The weighing bottle opening portion, placed in an oven at 110 ℃ ± 5 ℃ of (3.3), the drying 1h, taken out, placed in a vacuum desiccator (3.2) Cooled 30min, weighing, accurate to 0.0001g, repeat weighed to constant weight. 5.3.2 The sample (5.1) into the weighing bottle (5.3.1), and capped weighing, accurate to 0.0001g, partially open the cap, placed in drying Box (3.3), the control temperature of 110 ℃ ± 5 ℃, drying 2h, taken in a vacuum dryer (3.2), cooled 30min, reclosable bottle weighing, Accurate to 0.0001g, repeat weighed to constant weight. Calculation results of the analysis of 6 According to a formula of moisture content (%). 100% Where.
