Introduction

Cadmium is a natural element found in tiny amounts in air, water, soil, and food. All soils and rocks, including coal and mineral fertilizers, contain some cadmium. Most cadmium used in the United States is extracted during the production of other metals such as zinc, lead, and copper.
Breathing high levels of cadmium damages people's lungs and can cause death. Exposure to low levels of cadmium in air, food, water, and particularly in tobacco smoke over time may build up cadmium in the kidneys and cause kidney disease and fragile bones. Cadmium is considered a cancer-causing agent.

Principle

Atomic fluorescence spectroscopy (AFS) is the emission of radiation energy in the UV-visible region from gas-phase atoms that have been excited to higher energy levels by absorption of radiant energy. Usually, a flame is used to obtain the atom in a gaseous state. It is a radiative emission process that proceeds from the lowest singlet (S1) to the singlet ground state(S0).

Applications

Atomic Fluorescence Spectrometry (AFS) is an analytical technique that is primarily used to detect and quantify metals. It is an exceptionally sensitive technique that relies on exploiting the distinctive fluorescent spectra of each specific metal.
