The laboratory specialises in basic modification of samples (e.g. using laboratory scales, analytical scales, driers, muffle furnace, digestor, etc). In the laboratory it is posible to assemble experimental apparata, there are also several devices for distillation and extraction of samples, Kjehdahl apparatus for total nitrogen determination via distillation, etc. In the laboratory we study progressive oxide processes (AOP) and their combinations, we have e. g. Sander Ozonizer S 5 with power 0 – 500 mg of ozone per hour equipped with an air pump, glass UV Photochemical reactors LTD with volume 200 and 500 ml or with 400 W high-pressure mercury lamp, and the device for the sonification of samples.
