O knihe

Excerpt from Examination of Water for Sanitary and Technical Purposes

IN the period that has elapsed since the publication of the first edition Of this work, many processes for water analysis have been proposed, and we have included in the present revision such of these as seem to us of substantial value. In particular we may mention the methods recom mended by the Chemical Section of the American Associa tion for the Advancement of Science, and the application of the Kjeldahl process to the determination of the organic nitrogen. The adoption of the former methods will serve to secure uniformity in analytical data, while it is to be hoped that 'chemists generally will investigate and report on the latter, in order that a basis for the interpretation of results may be Obtained.

NO material change has been made in the description of the general Quantitative Analysis, in which we have followed to a large extent the methods indicated by Fresenius, selecting those best adapted to technical purposes.
