The rapid determination of nitrogen present as nitrate and ammonium is of great importance in the analysis of fertilisers, for often large numbers of nitrogen determinations have to be done. In the determination of total nitrogen, nitrate is reduced to ammonia with a reducing agent and the ammonia i

Instead of the classical conical flasks with volumes of 300 ml or more, a small so-ml flask (Fig. I: A) was used into which the sample could be weighed d.irectly.

A rapid method for the simultaneous determination of total chlorine and nitrogen in coal has been developed. The nitrogen isestimated in the usual way and the chlorine is absorbed in alkaline hydrogen peroxide and estimated gravimetrically. It is found that the time taken for both the determination
A novel method has been developed for the photometric determination of nitrogen oxides (NO,; NO and NO, gases). The sample .gas is shaken with an NaOH-alkaline H20, solution in a container so that all the NO, is converted to the NO; form. After decomposition of the H,O, by heating, the colour is dev
