Foreword

YS/T 3015 "loaded carbon chemical analysis methods" is divided into four parts. --- Part 1. Determination of moisture content of the dry weight method; --- Part 2. Determination of copper and iron content by flame atomic absorption spectrometry; --- Part 3. Determination of the amount of calcium and magnesium by flame atomic absorption spectrometry; --- Part 4. Copper, iron, calcium and magnesium content - Inductively coupled plasma atomic emission spectrometry. This section YS/T 3015 Part 1. This section drafted in accordance with GB/T 1.1-2009 given rules. This part is proposed by the China Gold Association. This part of the National Gold Standardization Technical Committee (SAC/TC379) centralized. This section is drafted.

Loaded carbon chemical analysis Determination of moisture content. Part 1 Dry weight method

1 Scope

YS/T 3015 provisions of this part of the determination of loaded carbon in moisture content. This section applies to the determination of gold carbon contained in moisture content. Measurement range. 10.00% - 40.00%.

2 Method summary

A certain quality of the sample, after drying, with the loss of quality as a percentage share of the moisture content.

3 instruments and equipment

3.1 Heated blast oven. with adjustable temperature control device, temperature error is less than ± 5 ℃. 3.2 balance. the maximum sample weight is not less than 1000g, a sense of the amount of 0.01g. 3.3 drying dish. enamel or corrosion-resistant material of the container, the sample size should be less than 2cm in thickness after tile. 3.4 dryer. built effective desiccant. Step 4 Analysis 4.1 Sample Weigh 100g ~ 500g sample (m0), accurate to 0.01g. 4.2 Determination of the number of Independently measured twice and averaged. 4.3 Determination The sample (4.1) into a known mass (m1) of the desiccator (3.3) of paving, 2cm or less in its thickness. Add warmed to 100 ℃ ~ 105 ℃ electric heated blast drying oven (3.1) inside, and dried in a desiccator (3.4) and allowed to cool to room temperature and weighed. Repeat dry Dry until constant weight (m2), the difference between the last two weighing less than 0.05% of the sample volume. Calculation results of the analysis of 5 According to equation (1) to calculate the moisture content w (H2O), expressed in%. w (H2O) = m0 m1-m2m0 × 100 (1) Where.
