Cobalt rarely occurs in natural water. It is used in the manufacture of alloys to<br />
increase corrosion resistance and strength. It is found in wastewaters as a<br />
corrosion by-product.<br />
APPLICATION: Industrial wastewater.<br />
RANGE: 0.00–2.00 Cobalt<br />
METHOD: PAN (1-2-Pyridylazo-2-Naphthol) forms a greenish<br />
complex with Cobalt (Co +2) at a pH of 5.<br />
SAMPLE Store samples in acid-washed plastic bottles. Adjust pH to<br />
HANDLING &<br />
PRESERVATION:<br />
less than 2 with nitric acid. Adjust sample pH to 5 before<br />
testing.<br />
INTERFERENCES: Iron (+2) and high concentrations of heavy metals.<br />
