摘要：

The methods of IR spectroscopic and gravimetric measurements of the adsorption of pyridine and ammonia were used to study the acid properties of zirconium oxide, modified by sulfate ions. It was shown that the total acidity and the ratio of the numbers of Lewis and Bronsted acid centers depend on the content of sulfate ions and the temperature of vacuum conditioning of the samples. It was established that the function of Bronsted centers is performed by hydroxyl groups. It was shown that pyridine and ammonia molecules, chemisorbed on acid centers, are additionally coordinated by SO42- anions.
