The Synthesis of a New Reagent For Detecting Cyanide
نویسنده
چکیده
This chemical sensor method was selected to detect cyanide in this paper. We synthesized a new reagent which can produce color change from colorless to yellow when encountering cyanide. According to this feature, this reagent can be used to identify cyanide. This reagent had also a good ability of anti-interference, the color change is not obvious when this reagent Encounter the interference ions of F-, Cl-, Br-, I-, No 3 -. So even though these ions are present with Cnat the same time, this reagent can also identify cyanide accurately.

A simple, sensitive, and non-extractive spectrophotometric method was developed for the determination of copper (II) using a newly synthesized chromogenic reagent, 6-(phenanthrene-3-yl)-1,2,4,-triazine-3-thione(PhDTT), in Tween 80 neutral surfactant. To synthesize the reagent (PhDDT), amyl nitrite was added to 3-acethylphenanthrene and refluxed for 26 hours to produce 2-oxo-2-(phenanthren-3...
