2.2.3. Testing influence of acid and hydroxide amendments
The tobacco plants were cultivated in the Hoagland hydroponic
medium containing UO2(NO3)2 (Lachema n.p., Brno, Czech Republic)
in the concentration 0.5 mM. The medium was supplemented either
with 0.1 mM acetic acid, 0.1 mM citric acid, 0.1 mM tartaric acid,
0.1 mM oxalic acid, 0.1 mM HNO3, 0.1 mM KOH, or 0.1 mM NH4OH,
respectively. Hoagland medium without any amendments was used as
a control. Samples for uranium uptake determination were harvested
after 7 days of cultivation.
