Product Description:

Iron is a very important plant nutrient element, and the content of iron in soil directly affects the absorption, utilization, growth and metabolism of plants. In the pH 2-9 range, hydroxylamine hydrochloride converts ferric to ferric and reacts with o-Phlorine to form orange-red complexes with characteristic absorption peaks at 510nm. The total iron content of soil can be calculated by detecting the absorbance change at 510nm.

Note: Before the experiment, it is recommended to select 2-3 samples with large expected differences for pre-experiment. If the absorption value of the sample is not within the measurement range, it is recommended to dilute or increase

Sample size for detection.
