Contributions to the Optimization of a Caprolactam Production Plant by Radiotracer Techniques

Residence time spectra and material distributions in an operating caprolactam production plant were measured by means of sodium 24, bromine 82 and technetium 99m. The results of the tracerexperiments contributed to an optimization of the plant.     

Application of 35S as a Radioactive Tracer for a Determination of the Composition and the Structure of Dispersion Coatings,Containing MoS2

A method is proposed for the determination of the content and distribution of MoS₂ in Ni-P-MoS₂, coatings deposited on a steel using ³⁵S as a radioactive tracer. ³⁵S is isolated and measured as BaSO₄. At the same time this approach gives the possibility to perform an autoradiographic investigation which enlarges the metallographic data.
