| Description | Silica sol - gel matter was examined as a binder assisting the preparation of agricultural soil sample pellets for elemental analysis by laser ablation inductively coupled plasma optical emission spectrometry. The sol - gel method, allowing homogenous dispersion of internal standard ( Sc) and analytes in calibration pellets, was applied to the determination of Cr, Ni, Cu, Zn and Pb in four types of soils. A Q-switched Nd:YAG laser ( 1064 nm) was employed for ablation of pellets prepared by pressing of a ground and homogenized blend of soil and silica gel. Calibration curves exhibited correlation coefficients greater than 0.997. The repeatability of determination for elements of interest did not exceed 7% RSD. Accuracy of determination was proved by X-ray. fluorescence analysis. |
