Red phosphorus is an important ingredient in the manufacture of pyrotechnic smoke and is likely to be in service for many years. One of the most effective ways to use smoke screens is to protect special vehicles from laser and infrared guidance systems. In this work, the formulation, obscurant and emission characteristics of the smoke composition in smoke devices used in special vehicles were determined and evaluated.

In this study, one analytical procedure was established for simultaneous determination based on UV-Vis spectrometry coupled with several multivariate linear regress solved by Python – an open language programme to quantify three antibiotics, including TET, PGP, and CEX, in laboratoryprepared synthetic and pharmaceutical mixtures. This study also provided a universally analytical procedure for determining the three antibiotics in their pharmaceutical forms without the need for optimization for each analyte.
