This article focuses on the adsorption properties of Ni-PEG / ZnO and Cu-PEG / ZnO catalysts. For modern technologies require more efficient and cheaper hydrogenation catalysts. Create them only through the development of new scientific approaches to the preparation of supported catalysts, and most recently modified polymer catalyst as supported on a carrier, and unsupported, involving the study of new physical and chemical methods. To determine the percentage of metal in the catalyst was prepared and investigated the mother solution.

Modern measuring instruments – a technical device, the purpose of which is to measure the unit of physical quantity. But do not confuse measuring instruments with indicators, the main purpose of indicators is to detect the presence of the measured physical quantity. Measuring instruments are an integral part of human life.
