Nitrogen-doped carbon-supported metal nano-particles show great promise as high-performance catalysts for novel energies, organic synthesis, environmental protection, and other fields. The synergistic effect between nitrogen-doped carbon and metal nano-particles enhances the catalytic properties. Thus, how to effectively combine nitrogen-doped carbon with metal nano-particles is a crucial ...

Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass. The principle of this type of analysis is that once an ion's mass has been determined as a unique compound, that known measurement can then be used to determine the same analyte's mass in a mixture, as long as the …

SUMMARY OF CHEMICAL ANALYSIS PROCEDURES Gravimetry and titrimetry This category includes the classical methods of gravimetry and titrimetry, and any separation tech- niques required to perform them, such as chro- matography and ion-exchange. However, gravimetric procedures for the analysis of ferrites are scarcely mentioned in the literature.

Gravimetric analysis is a class of lab techniques that uses changes in mass to calculate the amount or concentration of an analyte. One type of gravimetric analysis is called volatilization gravimetry, which measures the change in mass after removing volatile compounds. An example of volatilization gravimetry would be using the change in mass ...
