Description
Description
Hach 2651600 liquid reagent kit for chemical analysis of water.
Parameter: Cobalt / Nickel
Range: 0.01 - 2.00 mg / L Co, 0.006 - 1000 mg / L Ni.
Applications: water and waste water.
Method description [8078 - Cobalt]: After the sample is buffered and pyrophosphate is added to mask any Fe3+ , the cobalt reacts with 1-(2-Pyridylazo)-2-Naphthol indicator. The indicator forms complexes with most metals. After color development, EDTA is added to destroy all metal-PAN complexes except nickel and cobalt which can be determined with the same sample preparation. The measurement wavelength is 620 nm.
Method description [8150 - Nickel]: After pyrophosphate is added to buffer the sample and mask any Fe3+ , the nickel reacts with 1-(2-Pyridylazo)-2-Naphthol indicator. The indicator forms complexes with most metals present. After color development, EDTA is added to destroy all metal-PAN complexes except nickel and cobalt. Spectrophotometers automatically adjust for cobalt interference by measuring the absorbance of the sample at both 560 nm and 620 nm. This method is unique because both nickel and cobalt can be determined on the same sample with a spectrophotometer. The measurement wavelength is 560 nm for colorimeters.
