Atomic absorption (AA) is an analytical technique used to determine the amount of a substance present in a sample. It is a type of spectroscopy that measures the amount of a particular chemical element present in a sample. The technique can be used to detect elements in a wide range of concentrations, from parts per million (ppm) to parts per billion (ppb).

In atomic absorption spectroscopy (AAS), the sample is vaporized into a vapor containing a mixture of atoms. The vapor is then passed through a heated cell with a small opening, called a furnace. Inside the furnace, the atoms are exposed to a high-energy light source. The light source causes the atoms to be excited, which causes them to absorb the energy of the light and re-emit it at a different frequency. These absorptions and emissions are known as atomic absorption lines.

Atomic adsorption is the process in which atoms or molecules in a sample attach to the surface of a substrate. This can be used to detect the presence of a particular element in a sample. Atomic adsorption can be used to detect the presence of both organic and inorganic compounds.

Atomic adsorption is not as accurate as atomic absorption, but it is faster and much more affordable. It is used in many applications, including environmental analysis, biochemistry, industrial process control, and pharmaceutical analysis.

Atomic adsorption is a type of analytical technique in which a sample is adsorbed onto a substrate. The substrate is usually heated to a predetermined temperature, and then the sample is introduced into it. As the sample is exposed to the substrate, the atoms or molecules in the sample interact with the atoms or molecules on the surface of the substrate, and become adsorbed to it. This process of adsorption is called atomic adsorption, and the concentration of the element in the sample can be determined by measuring the amount of adsorbed material on the substrate.
