The characteristic concentration (1% absorption), detection limit, lnear range,coefficient of variation and recovery of the method of determination o f lead are 0. 0046, 0. 0044, 0-5.0 μg/ml, 0 .78 and 98. 5-102%, respectively.
It has been proved that the method of measuring Chlorine isotope which is based on Cs 2Cl + with graphite loading is the best one. But in some experiments we have found that the effects of SO 4 2- and NO 3 - shouldn’t be neglected.
Comparison of various theoretical models for quantitative analysis showed that the 'P/B-method' (determination of the background intensity under the characteristic peak) is the most suitable for semi-thick sections.
The low method determination limit makes the deoxyribose degradation reaction potentially useful as a new, highly sensitive and cost effective assay for iron quantification.
A photometric method of determination of activities of alanine and aspartate aminotransferases based on the use of L-glutamate oxidase and peroxidase has been developed.
