Description	Článek popisuje GC-MS identifikaci produktů úplné redukce herbicidů pikloram a klopyralid na rtuťovém dnu. Produkty redukce pikloramu, nalezené v silně kyselém prostředí, byly identifikovány. Jsou to 4-amino-3,5,6-trichloro-2-pyridínkarboxaldehyd, 4-amino-3,5,6-trichloro-2-pyridínkarbinol, 4-amino-3,5-dichloro-2-pyridínkarboxylová kyselina. Pri pH 3-4 nevzniká první produkt ale 4-amino-3,5-dichloro-2-pyridínkarboxaldehyd. 3,6-dichloro-2-pyridínkarbinol byl detegován v případě redukce klopyralidu. Na základě znalostí produktů elektrolýzy je diskutován redukční mechanismus z hlediska reduktivního štěpení atomů chloru v obou studovaných látkách. (cs) This paper presents the identification by GC/MS of the products obtained after the total reduction of picloram and clopyralid on a mercury pool electrode. The products found in the strongly acidic media reduction of picloram are 4-amino-3,5,6-trichloro-2-pyridinecarboxaldehyde, 4-amino-3,5,6-trichloro-2-pyridinecarbinol and 4-amino-3,5-dichloro-2-pyridinecarboxylic acid; at pH 3-4 the first compound is substituted by 4-amino-3,5-dichloro-2-pyridinecarboxaldehyde. For clopyralid 3,6-dichloro-2-pyridinecarbinol was detected. Under the light of such products the overall reduction processes are discussed showing the partial reductive cleavage of chlorine atoms in both cases.
