1. Preparing Standard multi element Solution
: 10 element before sample analysis, the ICP must be calibrated. Calibration consists of analyzing standards and a blank within the linear range of the element being analyzed.
The linear range for ICP-OES is 4 orders
Preconcentration of
elements from liquid samples was performed by means of a simple dried residue process, and spectral
evaluation was carried out by integration of the peak area (using WinQXAS/AXIL package software,
International Atomic Energy Agency (IAEA)) instead of the common net peak line intensity traditionally used
in conventional WDXRF systems. With the proposed methodology,
