Chloramines are compounds of chlorine and ammonia, combined chlorine (aka combined residual). Disinfection Breakpoint Chlorination. A MATLAB computer program was developed to calculate the concentration of the species with time and generate the breakpoint chlorination curves for a given contact time. Small changes, +-0.4, with pH between 7.2-7.8, TA around 80-120, and Borate near zero will be approximately correct. Between points 1 and 2 in the figure, mono- and di-chloramine are formed. The reaction is very fast and both ionized (NH4+) and unionized (NH3) forms of ammonia are removed. For background on what the various numbers mean, see Basic Pool Chemistry. > Free chlorine: combination of Cl2, HOCl, and OCl-.
