SKU: STEM-ST-0150-WXH
Rating: 5 (1 reviews)

Introduction

Tellurium is a rare and widely dispersed element, and it is widely used in rubber, petroleum catalytic cracking, enamel, glass, medicine industry, and many other fields. Tellurium is generally regarded as an element that human body does not need. It is toxic and harmful to humans and animals even at low concentrations. With the development of solar power industry, the widely used cadmium telluride solar cells will cause potential environmental hazards, so accurate determination of tellurium in environmental samples is nowadays very important.

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.
