Abstract:
1. A method of tracing a corrosive material, comprising the steps of: a) providing a system that contains a liquid; b) providing a corrosive material that contains one or more inert fluorescent tracers which has a detectable fluorescent signal in said system when placed in said corrosive material, wherein said inert fluorescent tracers are added to said corrosive material in a known proportion, and wherein said corrosive material is selected from the group consisting of concentrated HCl, concentrated H c) adding said corrosive material containing said inert fluorescent tracers to a liquid of said system; d) providing one or more fluorometers capable of detecting the fluorescent signal of said inert fluorescent tracers, wherein said fluorometers have a sample cell that corrosive materials can be placed in without rendering the sample cell unusable; e) using said fluorometers to detect and measure the fluorescent signal of said fluorescent tracers in said system; f) using the detected and measured fluorescent signal to determine how much of the corrosive material is present in the system; and optionally g) adjusting the operating parameters of said system such that the amount of corrosive material present is optimal for the operating conditions of said system.
