Photometric method for determining the concentration of reactions which proceed during formation or consumption of dispersion centers

摘要

1. A method for the photometric determination of the concentration of a reactant in a reaction in which scattering centers are formed or consumed in the sens of a transition from Rayleigh to Mie scattering where the peak rate of reaction Vmax and the time from the start of the reaction to the appearance of the peak rate of reaction tmax are determined and to obtain a single value for the concentration the functional relationship between concentration, Vmax and tmax is found empirically using a standard preparation, and Vmax and tmax are measured on the sample, which comprises choosing between the two possible concentration values on the basis of the 2nd reaction parameter, namely Vmax or tmax .
