## Abstract A procedure is described for the determination of tin, lead, bismuth, copper, iron, silver, cadmium and zinc in Sn‐Pb alloy, composed of ca. 50% Sn, 47% Pb, and 3% Bi, by means of atomic absorption spectrophotometry. The sample is dissolved in aqua regia. Tin and lead are determined aga
Flame atomic absorption spectrometry (AAS) and flame atomic emission spectrometry (AES) were used to determine calcium, copper, iron, magnesium, manganese, potassium, sodium, and zinc in 32 fruits. Samples were wet ashed using nitric acid and hydrogen peroxide and calibration was accomplished using
This paper describes a method of removal of the silicate phases in cements and clinkers by leaching with a maleic acid-methanol solution. Quantitative and qualitative deteminations by x-ray diffraction can be made on the minor compounds remaining after separation. These compounds include the ferrite
