<p><P>PROBLEM TO BE SOLVED: To prevent the occurrence of problem such as precipitation of non-adsorbed dispersant and detachment of the dispersant adhered to a solid, in a method of measuring the amount of adsorption of the dispersant. <P>SOLUTION: By a method of measuring the amount of adsorption of the dispersant, the amount of adsorption of the dispersant to a solid dispersed into a dispersion medium is measured by NMR spectra. For a measurement target, measurement concentration of the dispersant is obtained from strength of a prescribed NMR signal originating from the dispersant not overlapping with the NMR signal of the dispersion medium. For a reference, actual content concentration of the dispersant is obtained when the measurement concentration obtained from the strength of the prescribed NMR signal originating from the dispersant matches that of the measurement target. Based on a difference between the actual concentration content of the measurement target and that of the reference, the amount of adsorption of the dispersant to a solid in the measurement target is quantitated. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
