Method Name:
Aluminum, total recoverable, water, DCP. Official Name: Aluminum, atomic emission spectrometric, d-c plasma

Aluminum is determined by a direct-reading emission spectrometer which utilizes a d-c argon plasma as an excitation source (Johnson and others, 1979 a,b, 1980). A mixture of lithium chloride, sulfuric acid, and glycerin is added to samples and standards to provide a common background matrix and to compensate for viscosity changes. The liquid mixture is then converted by a ceramic nebulizer into a fine aerosol and introduced into the plasma via a plastic spray chamber and Pyrex injection tube. Aluminum is determined on the basis of the average of two replicate exposures, each of which is performed on a 10-second integrated intensity. Calibration is performed by standardization with a high-standard solution and a blank.

This method may be used to analyze finished water, natural water, industrial water, and water-suspended sediment containing from 10 to 1000 ug/L of aluminum. Samples containing more than 1000 ug/L aluminum and (or) with specific conductances greater than 10,000 uS/cm need to be diluted. Total recoverable aluminum in water-suspended sediment needs to undergo a preliminary digestion-solubilization by method I-3485 before being determined.

Stray-light effects in a high-resolution, single-element d-c argon plasma emission spectrometer are negligible.
