Using Infrared Spectroscopy to Measure Hydrocarbon Pollution Levels in Water.
Measuring the pollution levels in water so as to control CHC levels is important to protecting environmental and human health.
Developing a Method to Analyze Hydrocarbons in Water When examining CHC levels in water, the challenge is to use an ideal liquid-liquid extraction technique, to remove the water itself which would hinder with the measurement, with an environmentally friendly solvent.
Every different CHC has its own infrared fingerprint which can be identified with the aid of infrared spectroscopy.
Once identified, the quantity of infrared absorption can be used to establish the concentration of each CHC in a sample.
However, the halogenated solvents that the FT-IR technique used were sources of ozone-depleting chemicals, and so they were thought to be unsafe.
However, selecting the right FT-IR model for hydrocarbon analysis continues to be a challenge.
