Alimarin also advocated for the development of analytical chemistry and believed it to be a promising field of study. Alimarin presented his views on the general issues of analytical chemistry, such as its name and its importance, in a 1983 article titled "Modern Understanding of the Science of analytical chemistry".


Pedagogy

Alimarin held various teaching positions throughout his career. His lectures at the MITHT and later at the MSU focused on the practical aspects of analytical chemistry. Alimarin taught a general analytical chemistry course for second-year students at the Faculty of Chemistry at MSU and a special course on modern methods for students specializing in analytical chemistry. Over 80 doctorate theses were completed with Alimarin's guidance. Another 18 doctoral theses were defended with his advisory participation. Aliman also co-authored a textbook on analytical chemistry.


Legacy

The Department of Analytical Chemistry at MITHT is named after him.
