A review is given of the major contributions of Scandinavian chemists to analytical chemistry, illustrating the great importance of their work in development of the science as it is known today.
A survey is given of present-day analysis, from an editorial point of view, and suggests that though techniques have changed in order to meet the challenges of modern technological advances and materials, the fundamental character of analytical research and its publication has not.
A brief account is given of the work of Mohr, which is set against the framework of the development of analytical chemistry in Germany from early times up to the present.
In contrast to the earlier statement of one of the authors according to which conductimetric titration was invented by Küster and Grüters in 1903, it is shown that Ostwald made use of this analytical method as early as the nineties of the past century. Prior to Ostwald's work, however, papers appeared in which conductimetric curves were shown, with… (More)
A discussion is given of the problem of ascribing dissociation constants in the hypothetical situation in which the protons of the hydroxy groups of TAR and PAR dissociate in the reverse of the normal order, and it is suggested that the o-hydroxy group should be regarded as intrinsically as acidic as the p-hydroxy group, and that the change in pK due to the… (More)
The end-point of the direct complexometric titration of Al(3+) in pH 4.6 solution can be determined by monitoring the fluorescence intensity of the aluminium-morin complex, by use of a bifurcated fibre-optic light guide. The method allows the determination of aluminium in the 1-800 ppm range with good precision. The procedure is applicable even when the… (More)
A review is made of the factors affecting the accuracy of gravimetric methods, and which need to be investigated in the development of new methods. Recommendations are made for writing up such investigations for publication.
