✦ Synopsis

The application of lucigenin chemiluminescence for the determination of trace concentrations of kanamycin i described. The method is based on the inhibiting effect that kanamycin has on the reaction of lucigenin an hydrogen peroxide in a basic solution. The effect of the concentrations of the reagents was studied and the reactiol conditions are discussed. The proposed method allows the determination of kanamycin in the range of 1 X lo-l3 tl 1 x 10e5 M with a relative standard deviation of ca. 1.91%. The method is relatively free from the interference c common excipients accompanying the drug in pharmaceutical samples. The results obtained for the assay c commercial preparations compared well with those obtained by another known method and showed good accurac and precision.

## Abstract A weak chemiluminescence (CL) signal was observed during the mixing of isoniazid with lucigenin in alkaline aqueous solution. The CL signal was enhanced more than 100 times in the presence of potassium periodate. This CL system was developed for the determination of isoniazid using a fl

Hydrothermal studies showed the location of scawtite in the narrow internal tetrahedron foshagite-xonotlite-CO2-H20 of the system CaO-SiO2-C02-H20 and its compatibility with the calcium silicate hydrates in the 4-phase assemblages. The phase assemblages in this region involve scawtite, foshagite, xo
