Atomic absorption spectrometric method utilizing silver (Procedure A)To aliquots of fusidic acid stock solution (equivalent to 20-100 ng ml -1 ), two ml of 0.025 M silver nitrate solution was added. Solutions were protected from light, shaken and filtered (whatman No.44).

Atomic absorption spectroscopy

Atomic absorption spectroscopy (AAS) and atomic emission spectroscopy (AES) is a spectroanalytical procedure for the quantitative determination of chemical elements using the absorption of optical radiation (light) by free atoms in the gaseous state. Atomic absorption spectroscopy is based on absorption of light by free metallic ions. In

Determination of Trace Silver in Polymetallic Ore Samples

Rapid analysis of gold and sliver in blister copper by nitric

2012/9/5A rapid method for the analysis of gold and sliver in blister copper by atomic absorption spectrometry was proposed. Nitric acid was used to digest blister copper instead of commonly used sulfuric acid. This avoided forming the salt of copper sulfate in the filtration process when the volume of the mixture is very small. Thus, the time of filtration was saved. After filtrating, aqua regia was
