ABSTRACT:
A method for the quantitative determination of lithium in a liquid test sample employing turbidimetric or nephelometric techniques to measure the maximum rate of change in the optical density of a reaction mixture containing precipitated lithium. The lithium is precipitated by a lithium precipitating reagent to result in dispersed, suspended particles, and the maximum rate of change in optical density determined to provide a linear dose response which can be quantitatively correlated to the amount of lithium present in the test sample.
