ABSTRACT:
A method of determining the concentration of a quinolone in an aqueous solution comprising reacting the quinolone with an iron salt under conditions and for a time period sufficient to form a color change in the aqueous solution and comparing the resulting color change to an appropriate standard, and optionally comprising the further step of adjusting the pH of the aqueous quinolone solution to a value of less than about 7.0 prior to reacting the aqueous solution with an iron salt, as well as a test kit useful for carrying out such a method.
