Abstract
A new and convenient method for the rapid determination of aluminum in drinking waters using a.c. oscillopolarography in a lithium chloride system is described in this paper. The calibration graph is linear from 5 × 10−6 to 8 × 10−5 mol/L with a detection limit of 5 × 10−6 mol/L. The relative standard deviation of the method is 4.7% for 4 × 10−5 mol/L Al. Compared with other techniques, this method has the significant advantages of simple instrumentation, no deaeration procedure required and rapid measurement. It was particularly suitable to the analysis of 10−6 ~ 10−5 mol/L levels of Al in drinking waters.
