Calculation of precision in isotope dilution experiments.
Abstract Equations are derived for the composite error of isotope dilution measurements in three types of experiment viz. simple dilution, saturation analysis (sub-stoichiometric dilution) and adsorbed ion measurement; the latter two yielding equations of the same form. Errors for each type are derived in terms of radiometric errors, chemical errors and a factor related to the extent of isotope dilution. In general, dilution is the most critical factor which controls error; chemical errors are usually less important than radiometric errors. A nomogram for calculating dilution errors is given.
Cinétiques de transfert des ions phosphate du sol vers la solution du sol : paramètres caractéristiques
La nutrition phosphatee des plantes dans un sol peut dependre de la vitesse de renouvellement des ions phosphate de la solution du sol par des ions de la phase solide. Mais il n'existait pas jusqu'alors de methode permettant de determiner ces vitesses de transfert (...)
