Theoretical treatment of a model for analytical flame spectrometry

Theoretical examination of solute particle vaporization in analytical atomic spectrometry

“…All of the analysis and modeling presented here refers to the vaporization of individual particles. Extension to clouds of particles and complete aerosols is possible by using the approach developed in Li (6).…”

Depression of calcium, strontium, and barium signals by phosphine in atomic spectrometry

“…Near the primary reaction zone, the shape of the data curve is determined by the rate at which free atoms are being released from the rapidly moving analyte droplets. The free atom appearance rate is a combination of the nebulization, transport, desolvation, vaporization, and molecular decomposition rates (14). Factors which predominately affect the depletion of free atoms high in the flame are the diffusion of free atoms out of the flame and the formation of molecular and ionic species.…”

Vaporization and atomization of large particles in an acetylene/air flame

“…In yet another approach, ASV is used to measure reducible metal during a complexometric titration. Serial additions of metal are made to a solution containing ligands which form nonreducible complexes (1,(10)(11)(12). The end point ¡^related to the solution concentration of these ligands and the current magnitude is related to the conditional formation constant of the complex (13).…”

“…The vaporization process has been alluded to by a number of workers (4)(5)(6)(7)(8)(9) and suitable mathematical models exist for determining rates of vaporization under somewhat restrained conditions (10)(11)(12). These models incorporate the significance of particle size in their computation as well as the expected dependence on such parameters as flame temperature and partial pressures of the vapor components at the stated temperature.…”
