In 1913, Niels Bohr revised Rutherford's model by suggesting that the electrons orbited the nucleus in different energy levels or at specific distances from the nucleus. By doing this, he was able ...

Atomic Absorption Spectrometers use particular wavelengths of light to evaluate the concentration of gas-phase atoms in a liquid or solid sample. After a solid sample is dissolved in a liquid or a ...

Taking the soluble copper content in water quality samples as the research object, a mathematical model was established and flame atomic absorption spectrophotometry was used to analyze the ...
