along with free chlorine present in the sample to form a red color
which is proportional to the total chlorine concentration. To
determine the concentration of combined chlorine, run free

chlorine test from the results of the total chlorine test to obtain
combined chlorine.
Samples treated with sodium arsenite for manganese or
chromium interferences will be hazardous wastes as regulated by
