Short history

The Laboratory was set up in 1962 under the name of the Laboratory of Mineral Resources, later named the Laboratory of Mineral Resources and Water Chemistry, and recently the Laboratory of Ecological Chemistry.

The Laboratory was founded by Nicolae Labanov (1897-1972), dr. of chemistry, and afterwards modernized by Valeriu Ropot (1934-2002), dr. of chemistry.

Later, in 1991, the laboratory has been coordinated by acad. Tudor Lupascu, who reinvigorated it and the laboratory was renamed in Laboratory of Ecological Chemistry, focusing on the quality of the environment.

Research areas
  • Optimization of the obtaining and modification technologies of carbonaceous and mineral adsorbents for practical purposes;
  • Obtaining and studying of the structure parameters of carbonaceous and mineral supported  catalysts for their use in the catalytic processes of pollutants removal from underground and surface waters;
  • Synthesis and study of the new polyfunctional materials (including biologically active substances) by chemical and physico-chemical methods, useful for medicine, industry, agriculture and environment.
