1 The adsorption of ammonium ions by natural zeolite and Al 2 O 3 under static conditions has been investigated. The reason for changing the investigated solution pH during adsorption of ammonium ions on Al 2 O 3 has been grounded. A phase diagram of the twocomponent system has been constructed and the composition of the adsorption system in the state of equilibrium has been determined. The thermodynamic calculations of the adsorption system Al 2 O 3-NH 4 Cl-H 2 O have been carried out. It was established that the adsorption of ammonium with aluminum oxide occurs via the mechanism of physical adsorption.
The studies undertaken have established the effect of the ratio of acid tar coupled with straight-run petroleum tars introduced into the process. The influence temperature of the process, of final heating temperature of the bitumen mass in the reactor and of stirring intensity of the reaction mixture in the reactor on the quality is installed.

According to statistical data [27], the number of students of higher educational institutions of Ukraine decreased by ~ 10% compared to 2009, but compared to the data for 1999, it increased by almost 35%. However, the reasons for students to get an education 10 years ago were somewhat different. At that time, higher education in Ukrainian society was a sign of a certain status. However, now young people are getting higher education for the purpose of self-expression and self-realization, to achieve the set goal, to build a successful career in the chosen professional field. So,
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
