Abstract

The elemental analysis of a 1M hydrochloric acid leaching solution from soil samples in the mountain district of Shikoku was carried out by a portable liquid electrode plasma (LEP) atomic emission spectrometer. The contents of Na, K, Ca, Mg, Mn, and Fe were determined, and compared with those by flame photometry, flame atomic absorption spectrometry, ICP-MS and ICP-AES. The 600 V of the applied voltage was found to be suitable for the present sample solution at the use of a sample holder made of resin. The precision of the emission intensities for iterative measurements was improved by a normalization procedure with an emission line from the atomic hydrogen, and the relative standard deviations were ca. 20%. Results of quantitative analysis of soil-extracts by LEP atomic emission spectrometry were discussed based on geological data around the sampling area.
