Significance and Use
These test methods for the chemical analysis of cadmium are primarily intended to test such material for compliance with compositional specifications in Specification B440. It is assumed that all who use these test methods will be trained analysts capable of performing common laboratory procedures skillfully and safely. It is expected that work will be performed in a properly equipped laboratory.
1. Scope
1.1 These test methods cover the chemical analysis of cadmium having chemical compositions with the following limits:
| Element | Composition, max, % |
| |
| Antimony | 0.001 |
| Arsenic | 0.003 |
| Copper | 0.015 |
| Lead | 0.025 |
| Silver | 0.010 |
| Thallium | 0.003 |
| Tin | 0.010 |
| Zinc | 0.035 |
1.2 The test methods appear in the following order:
| Sections |
Antimony by the Rhodamine B Spectrophotometric Method
[0.0002 % to 0.0010 %] | 62-72 |
Arsenic by the Molybdenum Blue Spectrophotometric Method
[0.001 % to 0.005 %] | 40-50 |
| Copper by the Neocuproine Spectrophotometric Method [0.002 % to 0.030 %] | 10-19 |
Copper, Lead, Silver, and Zinc by the Atomic Absorption Method [0.004 % to 0.02 % Cu, 0.01 % to 0.05 % Pb, 0.004 % to 0.02 % Ag
and 0.01 % to 0.05 % Zn] | 51-61 |
| Lead by the Dithizone Spectrophotometric Method [0.001 % to 0.05 %] | 20-29 |
Thallium by the Rhodamine B Spectrophotometric Method
[0.0003 % to 0.005%] | 30-39 |
| Tin by the 8-Quinolinol Spectrophotometric Method [0.0025 % to 0.0150 %] | 73-82 |
