Instead of the green thallium lines that he expected, he saw a new line of deep indigo-blue.
Usually included in this category are gallium, indium and thallium; tin and lead; and bismuth.
Various tests eliminated the possibility of the unknown element being thorium, radium, lead, bismuth, or thallium.
At the end it is converted to thallium sulfate and the thallium is extracted by electrolysis on platinum or stainless steel plates.
Later in the week, they began to die because, as they left prison, they had been given thallium injections.
It is also effective in treating poisoning with non-radioactive metals, such as thallium.
Differences in thallium releases are a feature of the difference in process technology and are higher in the "dry" process.
The spectrometer uses a thallium-doped sodium iodide detector and carries out automatic gain stabilization every 60 seconds, allowing instrument drift due to changes in temperature and humidity to be reduced.
