The circulation of cobalt in the environment
 Charuza, Martin ; Mládková, Zuzana (referee) ; Sommer, Lumír (advisor)
This bachelor thesis deals with importance of cobalt in the environment, especially as a component of B12 vitamin. Vitamin B12 is a complex, that is necessary for proper formation of blood corpuscules and DNA, except that affects many others procesess in the body. Cobalt forms many complex compounds, which are discussed in this work. The most common oxidation number in compounds are +II and +III. The second part describes spectrophotometric determination of cobalt with suitable reagents. There are a lot of spectrophotmetric reagents for cobalt determination in a sample. The most widely used spectrophotometric reagents for determination of cobalt are 4-(2-pyridylazo)resorcinol (PAR), 1-(2-pyridylazo)-2-naphtol (PAN), 2-(5-Brom-2-pyridylazo)-5-diethylaminophenol (5-Brom-PADAP), 4-(2-thiazolylazo)resorcinol (TAR) a 2-(2-thiazolylazo)-4-methoxyphenol (TAMP). All of theese reagents are heterocyclic azodyes. Cobalt is bonded on this azodyes by coordination covalent bond and forms stable complex.
