R2CH−CR2−NH2+ HNO2→ R2CH−CR2N2NO → N2 + R2C=CR2 or R2CH−CR2OH This reaction has been used for analytical determination of primary amino groups in a procedure known as the Van Slyke method.
The main factor limiting the use of these models is the lack or low density and accuracy of the determination of primary soil properties needed to organize them.

The assessment involved several conservative factors including conservative determination of primary treatment efficiency, bioavailability, inhibition concentration, configuration of the nitrification process, as well as background zinc concentration in wastewater.
Secondly, code analysis and data analysis involving comparisons of fields and decomposition of fields are applied to extract attribute semantics from forms and table schemas, followed by the determination of primary keys, foreign keys and constraints of the database system.
In this work, a headspace solid-phase microextraction and gas chromatography coupled with mass spectrometry (HS-SPME-GC/MS) method for trace determination of primary aromatic amines was developed.
The technique of the analysis includes: (a) calculation of asymptotic cones of ground-based detectors; (b) modeling of cosmic ray detector responses at variable parameters of the flux of solar relativistic protons; (c) determination of primary solar proton parameters outside magnetosphere by comparison of computed responses with observations.
The AMS in the loess deposits was usually associated with the syn-depositional effects or the rearrangement during post-depositional alteration, although the obstacle still remains in determination of primary and secondary fabrics in the loess deposits (Lagroix and Banerjee 2004).
