An alternative mechanism of electrical conductivity in water is considered. Calculations of activation energies for flow and ionization show their proportionality. Therefore, it is assumed that during the water ionization, not intramolecular forces are in... see more

The mathematical analysis of data of titration of chloride polyhexamethyleneguanide (PGMG) containing repeating functional group, capable to a deprotonation carried out. For the characteristic of interparticle cooperation in system water - PGMG the method... see more

Aim. To study the acid-base properties of derivatives of 2-(benzoylamino)(1-R-2-oxoindolin-3-ylidene)acetic acid substituted by the location 1 of oxoindolin fragment.Results and discussion. The compounds studied are weak acids, their strength decreases wi... see more

The identification and analysis of chemical warfare agents and their degradation products is one of important component for the implementation of the convention. Nowadays, the analytical method for determination chemical warfare agent and their degradatio... see more

AbstractPb (lead) was a metal that does'nt regulated by water organisms so that the metal was constantly acumulated in organisms tissue. Currently, the pollution Pb in the waters of Indonesia have exceeded the maximum threshold of pollution defined by the... see more
