Abstract

Cyanogen chloride is a toxic chemical compound with the formula NCCl. This linear,
triatomic pseudo-halogen is an easily condensed colorless gas. More commonly
encountered in the laboratory is the related compound cyanogen bromide, a
room-temperature solid that is widely used in biochemical analysis and preparation.
This paper presents a description for Cyanogen chloride formation and creations, its
effects on animals and human bodies, and finally methods to control its percentages
in drinking water under the acceptable levels. The method of controlling its
concentration in water is summarized by using suitable chemical additives and noting
the time for settlement and then removed from the samples. A comparison between 4
additives in removing Cyanogen chloride is performed for the same sample of water.
It is found that as the concentration of NCCl increases the pOH of the sample
increases while pH decreases. Also, for the four additives NH4+, CN-1, Cl2 and
SO2 for the water samples, it was found that SO2 is the most efficient chemical
additive in removing CNCl since it needs the lowest time of removing CNCl.
