Conductometric diffusion rate method for determination of microgram quantities of ammonia.

摘要: Abstract 1. A microdiffusion rate method applicable to small samples (0.2 ml or less) containing less than 1 μg of ammonia nitrogen is described. 2. The diffusing into standard acid monitored by means conductance changes occurring in a specially designed electrodecell combination. Rate differences are shown be related the content from which was diffused. 3. basis for presented and some advantages shortcomings discussed.
