Description
Iron is ubiquitous on Earh's crust, it can be found in varying amounts in surface waters. It can can also be found in potable water especially when used as coagulant in water purification processes.
The determination ranges of the iron analyzer vary from trace μg/L to 200 mg/L using the (optional) internal dilution module. Ranges also depend on the chemical method used.
Method
In an acid buffered solution, ferrozine and iron react to form a purple colored complex measured at 572 nm. The absorption intensity is proportional to the iron concentration in the sample.
Reagents
- Iron ferrozine reagent kit 1l r1
- Iron ferrozine reagent kit 2l r1
- Iron ferrozine reagent kit 5l r1
- Iron ferrozine reagent ready to use 500ml r1
- Iron ferrozine reagent ready to use 1l r1
- Iron ferrozine reagent ready to use 5l r1

In a slightly acidic buffered solution, 1,10-phenanthroline and ferrous ion react to form an orange color in proportion to the iron concentration. The Fe(II)-phenanthroline complex is quite stable and measured at 430 nm. The absorption intensity is proportional to the iron concentration in the sample. A reduction of Iron(III) to Iron (II) must first be carried out in order to measure both iron species.
