BY INDUCTIVELY COUPLED PLASMA - MASS SPECTROMETRY SCOPE AND APPLICATION This method provides procedures for determination of dissolved elements in ground waters, surface waters and drinking water. It may also be used for determination of total recoverable element concentrations in these waters as well as wastewaters, sludges and soils. A new quantitative method for the emission spectrochemical determination of residual trace impurities in sponge copper powders has been proposed. The method is rapid, accurate and requires a rruumum amount of sample preparation. The lack of available powder standards made it necessary to use.

viewed signals for the determination of drinking water matrix elements (Ca, Mg and Na) and silica are acceptable.
The Ca and Mg data can be used in the calculation of hardness. When viewing sodium emission from the axial configuration, the ratio of signal intensity to analyte concentration is not a linear response.
Therefore, sodium should. Calibration Standard (CAL) - A solution prepared from the dilution of stock standard solutions.

The pre-concentration of Cu on a column packed with PCC was investigated. The opti-mum conditions for the preconcentration and desorption procedures were also elucidated. By applying the proposed method, the Cu contents in natural and drinking water samples were determined.
The natural concentration of metals in raw water which has not been treated or purified varies from state to state, country to country. It depends on many factors such as geological structures, the soil, the acidity of the water and the particulate matter concentration (Berman, ; Nriagu &.
